Most Mac users because of some features in the update don't want to upgrade to macOS Catalina. With Catalina update 32-bit application support has ended means your Mac will not run 32-bit applications after the update. Apple has been phasing out 32-bit applications for 10 years and now it has done so. But still uses ae not ready to accept as they have bought many 32-bit applications. Another reason is the iTunes, which it has been replaced with Music app. All your purchased music is there but it may not be organized as you had done in iTunes.

Part 1: Three Reasons Why User Don't Wanna Update to macOS Catalina

1. Using Very Old Mac OS System

Although MacBook Pro 2019 has been launched but still there are people using old MacBook OS. This is one of the main reasons why user don’t want to update to Catalina. There are users that hardly got aware of the last update completely and now with Catalina update they may find it hard to get aware of its features like Music replacing iTunes, restriction of 32-bit applications and new security measure taken by Apple. This may cost them plenty of time. But there are those people as well using older Mac models which will not support this new update. The only MacBook models Catalina supports are:

  • MacBook (Early 2015 or newer)
  • MacBook Air (Mid 2012 or newer)
  • MacBook Pro (Mid 2012 or newer)
  • Mac mini (Late 2012 or newer)
  • iMac (Late 2012 or newer)
  • iMac Pro (2017)
