I am using Paint Shop Pro since well before it was bought by Corel. Originally the company was called JASC. Albeit also having access to Photoshop for free, I always preferred Paint Shop Pro, as it is lighter and with some vector graphics features missing in Photoshop.Trying Corel paint pro 2020, hated the last version of adobe photoshop I bought
Although I am a long term Mac user, I generally switch to Bootcamp-Windows 10 for sound, photo and video editing as, since the upgrade to Sierra, Win10 makes my Mac significantly faster. Now with Catalina I systematically get a 30% performance boost using Win10 under Bootcamp...
It is really sad to see how badly Apple managed to cripple Mac OS, in their attempt to steer everyone to IOS.
But people needing professional usage for audio, photo or video editing are now left naked if they upgrade to Catalina...
So my suggestion is:
1) install Bootcamp and Win10
2) Install Paint Shop Pro
