failed upgrading high sierra
i use mac mini mid 2010 and recently tried installing high sierra but failed updating. Now when i open my macmini it shows installizing but after few minutes it says error occurred installing macos. I use wiressless keyboard for my macmini so i am not able to press any buttons. I went to the apple service center but they said it would cost me $40 and all my files would be removed. Do you have any suggestions?
Is this a good question?
