Illustrator 2018 - blocked on Mac OS High Sierra

They are not forcing you to update your Mac. They are not forcing you to update Illustrator. They are not deactivating older versions.

Maybe your preferences got corrupted.

Maybe you installed something on the computer that is not compatible with Illustrator.

The problem is: if you do not have the old installer, then you cannot uninstall and reinstall Illustrator. So you need to only take measures that do not include uninstalling. Did you already reboot the computer?

I wanted to add :
I noticed in my account, that it says Illustrator is "supposed" to work with OS 12.0 or higher.
So why isn't it working?

Hi,

I am just shocked and annoyed.

I pay am Adobe membership of CHF 65.95, and now - suddenly (out fo nowhere!) - I can't open my Illustrator app anymore on my 2017 Macbook Pro, running on High Sierra (10.13.6).
I checked with ChatGPT, and apparently it's highly probable that Adobe just deactivated older licenses.

So here's what I understand.
I pay a membership (and quite an expensive one), and now I can't even use the applicaitons I pay for !!!
It worked yesterday, and now today, I can't use it anymore !

What is this?
Is there a workaround ?
Or is Adobe forcing users to update their Macs to more recent OS ?

What if I enjoyed High Sierra? and don't want to upgrade my Mac.
I am getting so tired of companies forcing us to always update our devices / apps, etc... and then suddenly you have to buy a new Mac, a new Phone, download a newer version of an App, etc etc etc....
this is highly annoying !

If anyone has an idea on how to solve this, and how i can simply open and use Adobe illustrator, I'm all ears !

Many thanks,

Stephanie
