Before opening the issue, have you...?

• Searched for existing issues
• Looked through the wiki
• Updated MonitorControl to the latest version (if applicable)

Describe the bug

In this file https://github.com/MonitorControl/MonitorControl/blob/main/MonitorControl/Support/Arm64DDC.swift (and possibly the intel version), I don't see any CFRelease/IOObjectRelease calls, despite the fact that the docs say you must release the iterator and any objects as you iterate through them. But I'm not 100% familiar with swift, does it wrap iokit to take care of these things for you?

Also you should consider using CFSTR macro instead of CFStringCreateWithCString for the string constants that are fixed, so that way you avoid any runtime allocation entirely

Note that I have not traced through instruments to see how big of an impact this is

Steps to reproduce

• Read through code
• Notice no cfrelease/ioobject release calls

Expected behavior

• cfrelease/ioobjectrelease calls added as appropriate

Anything else?

No response
