Hello, Today I did setup my new desk / found the time to do it - as I moved back to France after few years abroad. I did purchase a while ago (more than 10 years) a 2.1 Harman Kardon speakers and decided to connect it to my MacPro for the first time. I never needed until now to use the external...

Hello, last year I had to equip my iMac 12.2 with a new graphics card (Quadro K1100M 2 GB) and so far I had no problems with Mac OS High Sierra. But since many apps (e.g. Office or Fusion) require a higher operating system, I took the plunge and installed Mac OS X Catalina using DosDudes...
