I questioned why Apple would ship my computer with Bluetooth devices that were compatible with the OS (High Sierra) on the computer. The advisors kept telling me that I should upgrade my OS from High Sierra to Mojave and the problem should be fixed. The problems continued and I kept contacting Apple Care and was instructed to try different “fixes”, make changes to System Preferences, update my High Sierra Software. I contacted Apple Care on November 29th and they told me the problem was probably due to having a wireless phone nearby. After restarting the computer the mouse & keyboard would be OK until they froze again. With both accessories frozen I could do nothing but turn the iMac off with the power button. Almost immediately, I began having problems with the Bluetooth mouse and keyboard freezing up, both randomly and after the computer woke from sleep mode. I purchased my Apple 27 inch iMac on Amazon and it was delivered to me on November 23, 2018.
