Hello and thank you for reply Yep, it would be helpful to know why I can´t use Metal Acc. My Mac has no exotic configuration, just a Retina5 2017 iMac with a running 10.14.2 on it. If there is any idea on why it won´t work please let me know on this way.

Since automatic update yesterday 1.7 won´t work. Every action, like erasing, cloning, etc. ends in Macs Paintball... at least I have to force quit AP again and again. What´s going on? Have reinstalled, try to uncheck "using Metal" (doesn´t work, its greyed out), only GPU etc. Nothing works. This is very, very frustrating. Any workaround or idea? Thank you. UPDATE: If you have probs like this uncheck "Metal hardware acceleration" and all is still working fine... umpff... mysterious. So sorry for my complaints...
