I have updated to macOS Catalina 10.15.1 successfully but it takes more than a minute to boot to the system.
Checking the output of the boot process the line
AGDCC: Unauthorized client 'PerfPowerService'...
Hi, I recently update to Yosemite, I feel that boot up slower than Mountain Lion, I recorded the boot in verbose mode. Please, anyone can help me? I see too many error messages, and load too many kext.
