I found a way some years back to get ilok trial unlimited amount of it on mac.
I'm using hackintosh by changing board id every 30 days or 15days I'm getting trial of ilok plugins.
But still this is pain and just posting so it can be helpful for some.
And this tricks might be already well known but just posting this is the only way I found to use slate digital soundtoys eventide and plugin alliance.
I do own some plugins from these brands
Sometime I subscribe on monthly plan
Honestly if I had enough money this year I would've bought soundtoys and PA cyberbundle

Extra notes
Some plugins like pulsar audio is 14 day trial also soothe 2
And kush audio is 10 day so one will have to change board id before 30 days depending on the plugin they want to use

 

so you have to keep deactivating and reactivating plugins before changing boardid?

 

No you don't have to just uninstall ilok and change board id on your configurator app for hackintosh clover/oc
And reboot reinstall ilok use temp email service like mail.tm
