FWIW, I have the same iMac mid 2010 and High Sierra is working perfectly. If you like you can submit an Etrecheck report. EtreCheck, created by one of own colleagues here in ASC. It is a diagnostic tool that's very useful to us in finding problems. Also it will give us further specs on your Mac. After it runs post the log file here. It will contain no personal information.
