Re-installing High Sierra over High Sierra?
Hi, I just installed High Sierra on an 2010 Mac Pro (still works like a charm, knock on wood) using an external USB thumb disk. But, after upgrading from Sierra, I am now getting the beach ball spinning when I do certain tasks and takes about 3 mins for the application to finally respond. Is it okay to re-install High Sierra again using the same method or should it be done another way? I have another internal drive with High Sierra installed with an USB thumb disk and no issues. Thanks
