Since I updated to Catalina, system preferences has been asking me to enter my iCloud password to finish setting up. I enter the password and it asks for my Mac password. I enter that and it asks for iCloud again. It just keeps looping. Oct 08, 2019 Several users have reported that an alert message saying “Update AppleID Settings” keeps appearing in Settings after upgrading to macOS Catalina. Furthermore, it seems that the message won’t go away and it just keeps asking users to update Apple ID settings on Mac, no matter what users do. Mar 13, 2020 To fix it, you will need to provide the password of the Apple ID that you see on the screen on your Apple Watch. Before you do that, make sure that your iPhone and Apple Watch are paired. When you tap on the Password button on the Apple Watch screen, you should see a. My new-to-me Mac Mini and Catalina are my first experience with MacOS. I’m just so tired of all the prompts for passwords freaking everywhere! It probably wouldn’t be as bad if I could just use the same password, but have to keep reviewing every single prompt to determine if my Mac is asking for my iCloud password or my Mac computer password.

We built Safari to be the best browser for your Mac, iPhone and iPad. Built-in privacy features keep your browsing your business. You can stream and search smarter with handy tools that help you save, find and share your favourite sites. Apple Pay in Safari lets you shop safely and simply. Safari for Mac is faster and more energy efficient than other browsers. And thanks to iCloud, Safari works seamlessly with all your devices.
Defending your online privacy and security.
Privacy and security aren’t just something you should hope for — they’re something you should expect. That’s why features to help protect your privacy and keep your Mac secure are built into Safari.
Intelligent Tracking Prevention.
Remember when you looked at that green mountain bike online? And then saw annoying green mountain bike ads everywhere you browsed? Safari uses machine learning to identify advertisers and others who track your online behaviour, and removes the cross‑site tracking data they leave behind. So your browsing stays your business. And Safari keeps embedded content such as Like buttons, Share buttons and comment widgets from tracking you without your permission. We know you’ll like that.
Sandboxing. Built-in protection for websites.
Sandboxing provides a safeguard against malicious code and malware by restricting what websites can do. And because Safari runs web pages in separate processes, any harmful code you come across in one page is confined to a single browser tab, so it can’t crash the whole browser or access your data.
Fingerprinting defence.
When you’re online, the characteristics of your device can be used by advertisers to create a “fingerprint” to follow you. Safari thwarts this by only sharing a simplified system profile, making it more difficult for data companies to identify and track you.
Protection from harmful sites.
Safari helps protect you against fraudulent websites and those that harbour malware — before you visit them. If a website looks suspicious, Safari prevents it from loading and warns you.
Private Browsing.
When you use Private Browsing, Safari doesn’t remember the pages you visit, your search history or your AutoFill information. You can also use DuckDuckGo, a built-in search engine that doesn’t track you, to make your web searches private too.
More secure and convenient passwords.
Safari works hard to make sure your passwords are robust and unique by automatically creating and storing strong passwords for you. Once stored, your passwords will autofill in websites across all your Apple devices and in apps on iOS and iPadOS devices. In Safari preferences, passwords that have been used more than once are flagged so you can easily update them. And one-time security codes sent over SMS are autofilled in the password field as soon as they appear in Messages. Security has never been so user friendly.
Surf seamlessly across all your devices.
Not only does Safari come on every Mac, it comes on all your iOS and iPadOS devices. And thanks to iCloud, your passwords, bookmarks, history, tabs and Reading List are always up to date no matter which device you’re using.
iCloud Keychain securely stores your usernames, passwords and credit card numbers, and keeps them up to date on your trusted devices. So you can easily sign in to your favourite websites — as well as in apps on iOS and iPadOS — and quickly make online purchases. And everything is protected with robust 256-bit AES encryption.
With Bookmarks in Safari, your favourite sites are always close at hand. Bookmark a web page on your Mac, and it automatically appears on all your iCloud-connected devices.
With Tab view, the last websites you had open on your Mac are available in Safari on your iOS and iPadOS devices — and vice versa. So you can go from one device to another without having to search for the web pages you were reading.
Save web pages you want to read later simply by adding them to your Reading List. Then view them on any of your iCloud-connected devices — even if you’re not connected to the internet.
The fastest way to browse on a Mac. And faster than any Windows browser too.
With an incredibly fast JavaScript engine, Safari is the world’s fastest desktop browser, outperforming both Mac and PC browsers in benchmark after benchmark on the same Mac.1

Search more. Stream more.
Safari is optimised specifically for Mac, so it’s more efficient than other browsers on macOS. And Safari plays HTML5 video — the format used by your favourite streaming services — whenever it’s available. So you can explore the web for up to three hours longer and stream video for up to four hours longer than on any other browser.2

The best browsing experience.
Features in Safari help you surf smarter and easily manage and share what you find.
Pay easily and securely with Apple Pay. Apple Pay is the easiest and most secure way to pay when shopping in Safari. Look for Apple Pay on your favourite shopping sites, then complete your purchase with Face ID or Touch ID on your iPhone or iPad. You can also use Touch ID on your MacBook Pro or MacBook Air, or double-click the side button on your Apple Watch. Your credit card details are never shared when you use Apple Pay, and your transactions are protected with industry-leading security.
Learn more about Apple PayUpdated start page. Easily and quickly access your favourites and frequently visited sites. And Siri suggestions indicate bookmarks, links from your reading list, iCloud Tabs, links you receive in Messages and more.
Desktop-class browsing on iPad. Safari now shows you a website’s desktop version that’s scaled for the large iPad display and automatically optimised for touch input. Faster and more fluid scrolling makes browsing feel better than ever. And a new download manager means you can easily download and share files directly in Safari.
Stop auto-play videos. Safari prevents unexpected and unwanted videos with audio from automatically playing while you browse. Just click the play button if you want to view them. Have a favourite site where you always want videos to play? Use per‑site settings in Safari to enable media auto-play.
Turn on website icons in tabs in Preferences to easily see what you have open. Pin your favourite sites and they’ll reappear in tabs every time you open Safari. You can also mute the audio on any tab directly from the Smart Search field — perfect for stopping the music without having to hunt for where it’s coming from or, if you prefer, silencing all the audio from your browser at once.
Personalise your browsing experience in Safari with settings for individual websites, like page zoom level, location services and content blockers. So each website appears just how you like it.
Automatically use Reader for every web article that supports it, so you can read without ads, navigation and other distractions. Customise your view by selecting your font size and style, and choose Sepia and Night themes.
Play video from a web page to your TV with Apple TV — without showing everything else on your desktop. Just click the AirPlay icon that appears on compatible web videos and you can watch your video on the big screen.
Float a video window from Safari over your desktop or a full-screen app on your Mac or iPad. Play the video in any corner of the desktop and resize it to see more or less of what’s behind it. So you can watch videos while you browse photos. Or catch up on your favourite show while you catch up on email.
With Spotlight built into every Mac, you’re never far from the information you want. As you type in the Smart Search field, you’ll see Safari suggestions from sources like Wikipedia, news sites, Maps, film listings, flight status, weather, stocks and sport.3
Share anything you come across on the web without leaving Safari. Just click the Share button, then choose how you want to send it off. Use Mail, Messages or AirDrop, or add it to a note.
Developers
Deep WebKit integration between Mac hardware and macOS allows Safari to deliver the fastest performance and the longest battery life of any browser on the platform, while supporting modern web standards for rich experiences in the browser. WebKit in macOS Catalina includes optimisations and support for additional web standards that enable even richer browsing experiences.

With more patchers are released and bugs are fixed, macOS 10.15 Catalina becomes better and better. But new macOS Catalina issues will never stop showing up. Thus, this article is worthy of reading as you'll know some common macOS Catalina upgrade issues, and how to address them.
1. Should I update My Mac to macOS 10.15 Catalina?
macOS Catalina is so tempting to upgrade, but you may still sit on the fence and wonder:
- Is macOS Catalina stable to use on My Mac?
- Is it worth updating to macOS Catalina?
- Will macOS Catalina damage or slow down My Mac?
More worries keep bothering you. Then, should you upgrade to macOS 10.15 Catalina on your Mac? To be honest, it's up to you as now macOS Catalina is getting less and less flaws.
If you want to try these new features mentioned in WWDC 2019, you can have a bash to install macOS Catalina. But keep one thing in mind, back up your Mac and everything before updating macOS.
If you are an conservative person who have get used to macOS Mojave or High Sierra, then just don't upgrade.
2. Can't install macOS Catalina on Mac
Normally, you can sign up to the Apple APP Store to download and install the macOS Catalina 10.15. But you could encounter problems while you are downloading or installing it.
How to fix:
If you are suffering from this problem, you probably need to check if you have enough space on the drive or volume for installation. The macOS Catalina update will take more than 4.9 GB in total.
Or you may not install to this volume because the Macintosh HD is not mounted when installing macOS Catalina, then you need to check your startup disk in Disk Utility.
Space is enough but the macOS installation couldn't be completed still? Well, you can boot your Mac into Safe Mode and reinstall macOS 10.15. This will isolate incompatible software when you update the sysem. Here is how to boot Mac in Safe Mode (also known as Single User mode).
- Restart your Mac and immediately hold the Shift button.
- When your Mac boot into Safe Mode, reinstall macOS 10.15 Catalina.
- Reboot your Mac.
Also, you may be unable to upgrade to macOS Catalina because of the error 'macOS Catalina could not be verified' below, even though you have cleared out your content caching and re-download for times.
How to fix:
- Click the Apple logo at the upper left and choose System Preferences.
- Find Date & Time and open it.
- Select Date & Time panel and Click the lock to make changes at lower left.
- Uncheck and then recheck the 'Set date and time automatically' option and then save changes by click the lock.
Then restart the computer and proceed to download the update once again through settings and software update. Hopefully, it will resolve the issue of the update not being verified.
3. macOS Catalina runs into low disk space during installation
Chances are that you still can't install macOS Catalina even in Safe Mode. Sometimes, even though you have pretty much no personal file on this Mac and space appears to be enough, you still could fail to install this system due to low disk space warning. As a matter of fact, it's just one of the macOS Catalina problems many users would face.
However, if you are disturbed by the low space problem, you received the low space warning from the system.
How to Fix:
You can fix the low space issue is to delete some local Time Machine snapshots which were made by the system previously. However, if you are not a specialist, you are not advised to do this deletion in case of losing data. Instead, if you have backups in Time Machine, you can just downgrade the macOS Catalina to another stable one like Mojave and then restore your lost files.
Some users see an additional Macintosh HD - Data volume in the Disk Utility of macOS Catalina and regard it as an unknown issue. Indeed, it's not. APFS drive in macOS Catalina will be divided into two volumes. One is called Macintosh HD which contains the system information and is protected with read-only mode, while the other one is Macintosh HD - Data volume where your apps and files are stored.
4. Can I install the macOS 10.15 alongside macOS Mojave?
You are torn if you don't know if macOS Catalina is better than Mojave or High Sierra. Maybe, you can make a compromise between them. That is to run macOS Catalina alongside your current macOS.
You can split your hard drive into two systems and install the Catalina on a separate partition. It is feasible because macOS Catalina will reside itself in a read-only volume, and you can do this with these steps:
Step 1: Open Finder and click Go at the upper left of your desktop.
Step 2: Go to Utilities and choose Disk Utility.
Step 3: Select the internal/startup hard disk and choose Partition at the top.
Step 4: Click Partition and click on the plus button +.
Step 5: Fill in a name, choose APFS format, and choose a size.
Step 6: Click Apply to create a new partition.
Step 7: When you move forward to install macOS Catalina, choose this partition as the installation location.
To switch between your current macOS Mojave and macOS Catalina, you can access System Preferences by clicking the Apple logo at the upper left of the desktop and select Startup Disk. Then click the lock at the lower left corner to make changes, key in the password as the system asks. Finally, select your system and restart your Mac.
5. Mac won't boot/turn on after installing macOS Catalina
If you breeze in the newest macOS and install it to your lovely Mac computer, only to find that your Mac won't turn on or stuck on the loading bar after update, or even gets stuck on Mac grey or white screen.

Why? Actually, it is because macOS Catalina doesn't support 32-bit apps anymore. Apple has been phasing out 32-bit software for the last 10 years and macOS Mojave is the last one that supports 32-bit software.
How do I check if my app is 32-bit on Mac?
By default, macOS will tell you that the app is 'not optimized for your Mac' or something like that when you attempt to open a 32-bit app in macOS Catalina. However, if it doesn't give any warning but the software just won't open, you can also check your apps for 64-bit compatibility manually.

Step 5: Find the target app and you will see a section titled 64-Bit (Intel).
Next to this section is either Yes or No. 'Yes' means the app is 64-bit, and 'No' means the app is 32-bit and needs to be updated.
How to fix:
Well, you can't have your cake, and eat it. If you want to upgrade your operating system to macOS Catalina which is only compatible with 64-bit software for sure, you can't use your 32-bit apps. So, you have only three options in this case and the solution is totally up to your preference.
- Upgrade this software to a newer 64-bit version.
- If there is no 64-bit version available for this app, find an alternative one that does the same work but is compatible with macOS 10.15.
