MacOS Mojave will be released in September 2018 bringing new features like Dark Mode, Dynamic Desktop, Mark Up tools in Quick Look and new apps from iOS. Find out if you can get Mojave and if it.
Announced in June 2019 at WWDC, the long-awaited macOS Catalina will be the 16th major release for Apple's operating system. There are tons of new features to be shipped, covering everything from iPad compatibility (Catalyst makes it easy to port iPad apps to Mac) to security (Gatekeeper will require Apple-notarized Developer ID for apps) to entertainment (new apps for Podcasts, TV, and Music), besides the usual improvements to all the native software.
While macOS Catalina is scheduled to be released sometime around September, the public beta is already available, so everyone can try all the new functionality without the wait. Read through our step-by-step guide to learn how to install macOS Catalina public beta.
Is My Mac Compatible With macOS Catalina?
Regardless of whether you want to install the beta or wait for the official public release, one question will inevitably pop up in your head — is my Mac compatible with macOS Catalina? Good question! Let’s look at the Mac OS Catalina compatibility chart to find out.
List of macOS Catalina supported Macs
Overall, due to the numerous efficiency improvements under the hood, macOS Catalina supported Macs are nearly identical to those of macOS Mojave:
The only difference you might find is the new Mac OS Catalina requirements not covering Mac Pros ranging from 2010 to 2012. So unless you have that specific Mac Pro model you should be able to try the new operating system.
However, in case your Mac is on the older side, barely managing to load the macOS won’t result in a pleasant experience. For example, Apple specifies that running 4K as well as Dolby Atmos content will only be possible with Macs introduced in 2018 or later that boast 4K screens.
But don’t hurry to the Apple Store just yet. If watching videos in 4K is not an absolute necessity, you could simply optimize the Mac you have for faster performance and run macOS Catalina without a problem.
What are macOS Catalina storage requirements?
To run properly, macOS Catalina needs a considerable amount of disk space. It’s generally recommended to keep at least 15% of your main drive free. But remember, you’ll also need space for future macOS updates and all the new software that goes with Catalina. So you should think of freeing up storage way beforehand, while you’re still on Mojave or other older OS.
The general space goals to aim for here:
Upgrade smoothly: remove outdated system files
The best way to rise above the basic Mac OS Catalina requirements is to do a thorough scan of your Mac and purge all the useless data that you’ve accumulated over the years. Quite a hefty task if you choose to do it manually: your Mac has a ton of system files and invisible folders that require the use of Terminal to get to. Luckily, there's a software designed to take care of it all automatically.
CleanMyMac X is the easiest and the most thorough way to bring your Mac back to its pristine original state. In fact, the app is so helpful and intuitive that it was recognized as the “#1 Product of the Month” by Product Hunt.
Here are the kind of files you should try to get rid of:
To do so with CleanMyMac X, simply:
Even though I’ve been using CleanMyMac X on a regular basis, the System Junk scan has revealed over 11 GB of files I no longer need. Imagine how much dead weight your Mac can carry!
Maximize your storage space
Once you clean your Mac from all the system and user-generated junk, you’ll notice improvements in responsiveness and speed right away. But it’s not only outdated files that slow your Mac down.
To hit all macOS Catalina system requirements, you need to have as much of your hard drive free as possible. This might include, for example, legitimate but long-forgotten documents you haven’t opened in years.
The good news is you can see what’s taking up your hard drive capacity with a new feature in CleanMyMac X called Space Lens, which creates an interactive visual map of all your files and folders:
With no extra system files or unused heavy folders dragging you down, your older Mac will become brand new again, agile enough to take on the new macOS Catalina as it becomes available this fall. Best of all, just one app — CleanMyMac X — can do it all for you.

A year ago, it took me two days to update my Mac to the latest macOS, High Sierra, and I wrote this post to document the performance issues I encountered.
This year? Less than two hours!

Yes — I mean from preparing my Mac for Mojave update, downloading the Mojave pack from App Store and installing the new OS, to finally being able to experience the new elegant Dark Mode — the whole process took less than two hours to complete.
First impression — macOS Mojave is much better than High Sierra, both in performance and UI experience.
However, I did come across a few performance issues with macOS Mojave. For example, it randomly froze up for a few seconds, the new App Store was slow to launch until I force quit it, and there were several other small issues.
I’ll share those issues here. Hopefully, you can find some hints to solve the problems you are facing, or speed-up tips to increase your Mac’s performance.
First Things First: If you’ve decided to update your Mac to macOS Mojave but have yet to do so, here are a few things to check before you upgrade. I highly recommend you take a minute to go over the checklist to avoid potential data loss and other issues.
Also, if you are using your Mac for work, do not update the machine right away as it may take more time than you thought. Instead, do it at home if possible.
Ready to go? Great. Now go ahead and update your Mac. If you encounter a problem (hopefully you won’t), here are a list of issues and solutions you may want to look over
Note: It’s very unlikely that you’ll face all the performance issues below. Just navigate through the Table of Contents below; it’ll jump to the right issue and provide more details.
During macOS Mojave InstallationIssue 1: Mac gets stuck during installation and won’t install
More details: Normally, once you download macOS Mojave installer, all you need to do is follow the instructions (e.g. agree to software license agreement, input login password, etc.) and the new macOS installs on your Macintosh HD automatically. But you may see one of the following pop-up errors, or something similar:
Possible Reason: Your Mac isn’t eligible for the Mojave update. Not every Mac machine can be upgraded to the latest macOS. It must meet these basic hardware and software requirements. For example, If you’re using a MacBook Air or MacBook Pro, it must be Mid-2012 or newer and have at least 4 GB of RAM (preferably 8 GB), as well as 15-20 GB of free disk space.. For example, If you’re using a MacBook Air or MacBook Pro, it must be Mid-2012 or newer and has at least 4 GB of RAM (preferably 8 GB) and 15-20 GB of free disk space.
How to Fix:
Issue 2: Installation is Stuck at “About a Minute Remaining”
More Details: The Mojave installation stops at 99% and won’t move forward; it’s stuck at “About a minute remaining”. Note: personally, I haven’t encountered this issue but last year I did while upgrading to the macOS High Sierra.
Possible Reason: Your Mac is running an older macOS version–for example, macOS Sierra 10.12.4 (the newest Sierra version is 10.12.6), or macOS High Sierra 10.13.3 (the newest High Sierra version is 10.13.6).
How to Fix: Update your Mac to the newest version first, then install macOS Mojave. For example, if you are on Sierra 10.12.4, first open Mac App Store, click the Update button under “Updates” tab, upgrade your Mac to 10.12.6 first, and then install the latest macOS Mojave.
Note: My MacBook Pro was running High Sierra 10.13.2 and I had no problem directly updating to Mojave without updating to 10.13.6. Your mileage may vary, especially if your Mac runs Sierra, El Capitan, or an older version.
After macOS Mojave is InstalledIssue 3: Mac Running Slow on Startup![]()
Possible Reasons:
How to Fix:
First, check how many Login Items you have and disable those unnecessary ones. Click on the Apple menu on the top-left corner and select System Preferences > Users & Groups > Login Items. Once you’re there, highlight the apps you don’t want to auto-start and hit the minus “-” option.
Next, check if you have got some “hidden” launch agents on your Mac. To do so, the easiest way is to use CleanMyMac, under Speed module, go to Optimization > Launch Agents, there you may see a list of helper/service applications, feel free to disable or remove them. This will help speed up your Mac’s startup speed as well.
If the startup disk on your Mac is almost full, you need to free up as much disk space as possible. Check out this article that shows 10 useful techniques to gain more storage, as well as tips to prevent your hard disk from filling up.
Lastly, if you are on an old Mac with a spinning hard drive or Fusion Drive rather than solid-state flash storage, chances are it will take much longer to start up. There’s no fix for this except swapping out your old hard drive with a new SSD.
Issue 4: Mac App Store is Slow to Load and Shows Blank Page
More Details: Excited to see how the brand new Mac App Store looks in Mojave, I tried to open the app immediately after macOS Mojave was installed. However, I ran into this error: a blank page?! I waited for at least a minute hoping to see the new interface, but it didn’t work.

Possible Reason: Unknown (perhaps a macOS Mojave bug?)

How to Fix: I tried to quit App Store, only to find that option was greyed out.
So I went to Force Quit (click Apple icon and select “Force Quit” option) and it worked.
Then I re-opened the app, and the brand new UI in Mac App Store worked perfectly.
Issue 5: Web Browser Freezes
More Details: I mainly use Chrome on my Mac. While I was writing this article, my Mac froze up a bit–that spinning rainbow wheel showed up and I couldn’t move the cursor for five seconds or so.
Possible Reason: Chrome is probably the culprit (that’s my hunch at least).
How to Fix: In my case, the random freeze only last for a few seconds and everything went back to normal. Out of curiosity, I opened Activity Monitor and noticed that Chrome was “abusing” the CPU and Memory. So I think it’s the culprit.
My first suggestion to those of you who are facing Safari, Chrome, Firefox (or any other Mac web browser) issues on macOS Mojave is this: update your browser to the latest version. Meanwhile, try to open as few tabs as possible while you are surfing the Internet. Some web pages can “abuse” your Internet browser and system resources in the form of annoying display ads and video ads.
If the issue still persists, check if your Mac has Adware or malware. You can do this with MalwareBytes for Mac or Bitdefender Antivirus for Mac.
Issue 6: Third-party Apps Running Slowly or Unable to Open
Possible Reason: The apps may not be compatible with macOS Mojave thus are unable to run smoothly.
How to Fix: First of all, open Mac App Store and go to the “Updates” tab. Here you’ll likely see a list of apps available for updates. For example, I found Ulysses (the best writing app for Mac), Airmail (the best email client for Mac), along with a few other Apple apps waiting to be updated. Simply hit “Update All” and you are good to go.
For those third-party apps not downloaded from App Store, you’ll have to visit their official websites to see if there are new versions optimized for macOS Mojave. If that’s the case, download the new version and install it. If the app developer has yet to release a Mojave-compatible version, your last option is to find an alternate program.
Issue 7: iCloud Sign-in Slow
More Details: While macOS Mojave was still in beta, I heard about some iCloud bugs from the App community. I tested it myself and found the sign-in process was surprisingly slow. It took me about 15 seconds. At first, I thought I put in the wrong password, or that my Internet connection was weak (turns out it wasn’t the case).
Possible Reason: Unknown.
How to Fix: Wait a few more seconds. That’s what worked for me. I then was able to access the data stored I have stored in iCloud.
Finally, the “Next” button is clickable
Final Thoughts
This is the first time I ever immediately updated my Mac to a major new macOS. Previously, I always waited for those brave early birds to test the water. If the new OS is good, I’ll update one day; If it’s not, forget it. Remember the security bug that popped up shortly after macOS High Sierra’s public release? Apple had to push out a new version, 10.13.1, to fix that and the incident generated a lot of criticism in the Mac community.
I didn’t hesitate to update this time. Maybe I was too impressed by the new features in Mojave, I don’t know. I’m glad that I chose to upgrade, and quite happy about the performance of Apple’s macOS Mojave overall–even though there are some performance issues related to the new OS or the apps I’ve installed.
My advice to you is this: If you’re using a brand new (or relatively new) Mac computer, updating to Mojave is a wise decision. It won’t take you much time, and it’ll save you the hassle of being bothered by Apple’s annoying update notifications. Plus, Mojave is really awesome. Do make sure to back up your Mac data before you upgrade just in case.
