Do you have any suggestions for other repairers of this (or similar) product?
Apple owners want to stick with MacOS even when Apple doesn't support this product and they appear to get a lot of pleasure from buying a new Apple product. So OpenPatcher is the only way to save their perfectly functioning Apple computers from being replaced and it appears to work very well, if detailed installation and patching instructions are followed.
