just tone and no boot after Mac mini mid 2010 16GB upgrade
After installing the upgrade the mac is just generating a tone every 4-5 second and does not boot. I saw on the guide page that at least 2 other users had the same problem. Anybody has an idea of what to do?
I am running high sierra on that mac but, with only 2GB, it is struggling, hence the temptative upgrade…
Is this a good question?
