Get Urgent Same Day iMac Computer Performance and iMac Troubleshooting Help: iMac Will Not Start Up, Power On, or Boot Up
If your iMac will not start up, power on, or boot, Keith Thomas provides urgent software assistance. Hardware repairs are not included or viable for any Intel iMac computers, and Apple will not service the iMac 2019 computer.
Important: Intel‑based iMacs, including the 2019 model, no longer run macOS reliably. Apple has ended or is ending service for these models, which are now six to seven years old. Hardware repair is not a viable option if the computer is not powering on, an option to use an external USB-C as a MacOS startup option can help if a new iMac computer is not the option for you.
Instead, Keith Thomas offers software troubleshooting, update assistance, and migration guidance to help you move forward if you decide to buy and purchase a new Apple Mac Computer. Keith Thomas provides a professional iMac Intel to Apple iMac Silicon migration service, which Apple does not provide for a clean MacOS installation and setup with a new Apple iMac computer.
