So today I woke up and when I turned on my Mac I found out there was an iStat Menus update. Still a little bit sleepy and not reading it carefully I clicked OK on every pop up that appeared. When the update was complete I was shocked to find out that I was now running iStat Menus 4 and that my license key for iStat Menus 3 didn't work anymore. I feel a little bit cheated because it wasn't not so long ago that I spend 16$ USD and now they're asking me to pay 9$ USD more in order to 'upgrade'. I don't want to upgrade, there's no difference between the version 3 and the newer version, and even if they changed the design a little bit, I simply don't care. Is there a way to get back to the previous version with the same serial key I was using so far? or have I been scammed and now have to spend 9$ USD in order not to loose the access/usage of this application completely? And yep, for me 16$ USD is a lot of money. Don't even bother commenting on how I spent 1000+$ USD on a Mac and not being willing to throw some more money in order to get an application.
