Last week when I turned on my Mac mini, I got a kernel panic and when I tried to turn it on again, I got three beeps and then nothing. I took it to an Apple dealer. They replaced the RAM and my system booted again. I took it home and plugged it in, expecting that it would boot up normally like it did in the store. But instead, it started to boot up in (what seemed like) safe boot but after the gray bar was filled up about a quarter, it stopped. So I tried to boot it up in recovery mode, but then again I got a kernel panic and now I only get the three beeps again. I'm afraid the motherboard is nuking the RAM modules or something like that ... is that possible? They were new RAM modules, I paid 85 EUR for them Any ideas?
