Catalina Patcher Firmware Update Required

Posted on by admin

  1. If you did any mods with the 10.15 Catalina install app that is why it won't create a patcher I re-downloaded the 10.15 beta app and I successfully created a patcher but it says I need a firmware update on my MacBook 5,1. doublepost= /doublepost Yes I used your APFS rom patcher on both my MacBook 5,2 and iMac 9,1 both say needs.
  2. This message pops up when trying to update an iPhone 11 to IOS 14 on Mac running Mojave using iTunes. ITunes is up to date. Apple Support says my OS must be updated to Catalina to work with IOS 14. Has anyone seen this message using an OS earlier than Catalina? If so, did you select the option to do the Install?

There is nothing on the screen during this process.While I do not need the catalina patcher as my mac natively supports Catalina, I am hoping that solving this issue with the firmware updates will resolve the other issues with the official installers.Note I have reset the SMC and NVRAM loads during this and it doesn't appear to do anything.

If it does not work, try to restart the router itself. Sometimes, it’s the ISP that’s having problems. To restart your router, switch it off, wait for 10 seconds, and turn it back on.

Now, if restarting the connection and the router doesn’t resolve the problem, restart your Mac in Safe mode and check if the WiFi is working.

Here’s how to restart your Mac in Safe mode:

  1. Turn off your Mac.
  2. After you hear the startup tone, press the Shift key and hold it.
  3. Release the key the moment the Apple logo appears.
  4. Choose Safe Boot from the list of options on the startup screen.

If the WiFi is working fine in Safe mode, it is likely that incompatible extensions and apps are causing the problem. Fix it by installing the app and extension updates that are compatible with Catalina.

To update apps and extensions, follow these steps:

  1. Go to the Apple menu.
  2. Select System Preferences.
  3. Choose Software Update to check for any updates.
  4. If an update is available, click the Update Now button next to it to start the installation.

Should you wish to automatically install apps and macOS updates in the future, do steps 1 and 2. And then, choose Automatically keep my Mac up to date. When your Mac detects new updates, it will send you notifications.
