Now this is how it looks when you install an Adobe app on MacOS, for example Photoshop:
I mean ... Is all this crap really useful? Can't Adobe integrate it into the app instead of making 2 million independent apps?
In addition, Adobe processes run in the background to do unwanted tasks. Sometimes my internet connection is slow, I look at where it's coming from and see that it's coming from a "Setup" process. I look closer and it's actually an Adobe process, downloading gigabytes and gigabytes of data while taking up my entire connection and preventing me from doing anything.
I would like to point that I have NO adobe application running, nor Creative Cloud, and that I did uncheck the option that automatically launches Creative Cloud at startup. But still Adobe runs a lot of processes in the background, downloads gigabytes of data while all my apps are actually up to date. What is it downloading?! How I can prevent Adobe from doing tasks that I don't want ?
This is an age-old complaint, starting around CS2 or 3 as I remember.
I could sympathize if there was any evidence that it actually impacted performance, but I have never seen that. Lots of people claim it does, but as a convenience blame and never with any supporting evidence. They usually have general system problems (bad video drivers, tablet drivers, third party plugins/extensions etc).
I have all this and more, and it has never bothered me for a second. Any advanced application nowadays will install a bunch of these background processes. I disable from startup those that I obviously don't need, and leave the rest.
