Once can have a lot of difference between the use of Mac OS Catalina and Mac OS Mojave. You are not restricted to use either of the Mac OS in place of the other since the difference is not that much. You can install either Catalina or Mojave is you had one initially because of that. The best things about Mojave is that you can have the support for the older Mac pro models. The only challenge that you have in Catalina is that you cannot support older Mac pro models with the use of metal cables. After the upgrade of the software that has a 32 bit processor, you cannot use in Catalina, since it does not support 32 bit programs. Developers were asked to do some upgrade on Mojave since it was the last Mac OS with 32 bit architecture. One of the most significant things about Catalina Mac OS is that it uses 64 bits architecture. Despite the fact that 32 bit processor is obsolete, you need to consider taking an app that has a 32 bit processor to the next level.
When you compare a 32 and 64 bit processor, you can realize that a 64 bit has a higher performance that can allow up to 4GB of RAM. It is important to put some things into consideration before you upgrade to Catalina. The first thing that you need to do is to confirm the Mac OS for 32 bit applications. The next thing that you need to do is to allow the past be gone. If there is an application that has a 32 bit structure you wat to use them, you can look for any available upgrade.
When you get the best upgrade, you need to clean you Mac pro by uninstalling all the outdated 32 bit applications. Mojave keeps all the media in iTunes like all other old Mac OS. Due to some simple reason, iTunes in Catalina is divided into three different apps. The division of iTunes into three different apps is because one iTunes app carries more than enough. When you upgrade, your medial get to move automatically to their respective iTunes apps.
You get to have the best workflow due to the availability of dark mode that adjusts the display of the desktop with the help of Mojave. With the help of stacks, you can have a better file management system in Mojave. The experience with Catalina is even better than Mojave since you have a healthy Mac life balance due to the expanding of the workspace.
