A big update from Apple as the company released the most awaited update for its OS – macOS Catalina. It has added a plethora of new features, apps, and user-friendly enhancements to name a few over the company’s line of Mac PCs like the iMac, MacBook and many more. Though most of the newly added features are captivating, you got to hold for a while to download the update. The issues are obvious, you face the same old typical headaches making the users unnerved while installing the upgrades. The update for Catalina will change the apps you use on your Mac machine.

While running macOS Mojave or the higher versions like High Sierra, a pop-up box comes out the next. Similar is the story with the newer macOS Catalina, as you can see a similar sort of pop-up box that is used to start your app the message “needs to be updated” appears on the top. Once you upgrade to Catalina, the apps that give up this error will fail to run at all. However, the issue has a lot to do with Apple’s transition from 32-bit to 64-bit apps. The latter seems more competent than the former counterparts as they can reap better benefits with its robust 64-bit multi-core processors, and thus tap with larger sizes of RAM and more.

Moreover, these apps can access more amounts of memory, thus enabling quicker system performance, and thus leverage the technologies, which further define the current Mac experience, like the Metal graphics acceleration and so on. Apple has claimed to switch from 32-bit to 64-bit apps for a quick transition for a decade but little has done on this issue. With this, if you are more relying on any particular 32-bit app then take note, it will not work in macOS Catalina as many users have experienced the same.

In the meantime, a few popular apps including Adobe Photoshop tend to suffer from temporary compatibility issues with the said OS update of Catalina. Hence it better late than never and try things only after upgrading until a software patch sorts out those issues. If you want to check which of your applications are still on 32-bit on your Mac, check the same on the Apple menu and click System Report.
