19,000. It's just started working, after 5 hours of waiting. Having read some other forums, and Apples website info, seems I need to take my Imac to a store, for a firmware upgrade! Seriously, why? I don't have the time and theres not a store, anywhere near me, it's 2 hours to the nearest store! Madness.
When Monterey was installed, any Firmware ( Boot ROM updates ) ) would have been included within the Monterey Installation.
Apple has ceased to offer Firmware ( Boot ROM updates ) Updates as a Standalone for many many years.
There are reports appearing on the ASC Forums regarding failed installation of Monterey on older Qualifying Apple Computers. In most cases this is related to having a NON Apple Original internal drive ?
The EFI Boot ROM included in Monterey is verifying for Original Apple Drive and if not found , may Balk or fail to upgrade to Monterey.
Reports indicate the EFI BOOT ROM is Required to Flash the Computer and is a requirement for a Successful Monterey Installation.
