Subject: [PATCH] Exclude CPUFriend from El Capitan-maxed Macs

iMac8,1 reported heavily degarded performace, most likely due to the data given to ResourceConverter.sh

+# Platform Plugin Plists
+
+This folder contains many profiles for CPU power management. These plist were originally provided by Apple within IOPlatformPluginFamily's `ACPI_SMC_PlatformPlugin` and `X86PlatformPlugin`, then converted into CPUFriend compatible data via [ResourceConverter.sh](https://github.com/acidanthera/CPUFriend/blob/master/Tools/ResourceConverter.sh).
+
+This allows for all Mac models in this patcher to support the correct power management regardless of the SMBIOS used.
+
+* Note: iMac7,1 and older did not support ACPI_SMC_PlatformPlugin so no CPUFriend support is required
