🛠️ Scenario A: Stuck on a Specific Screen
If your Mac isn’t reaching the desktop, the icon on the screen tells us exactly what’s wrong:
Folder with a Question Mark: Your Mac can’t find its operating system.
The Fix: Shut down, then hold Command + R (Intel) or the Power Button (Apple Silicon) to enter Recovery Mode and use Disk Utility to “First Aid” your startup disk.
Prohibitory Symbol (Circle with a line): Your Mac found an OS, but it’s not compatible with your hardware. This often happens after a failed update.
Blank Black or Gray Screen: This is usually a power or display issue. Try a “Hard Restart” by holding the power button for 10 full seconds.
🧹 Scenario B: Doing some “Spring Cleaning”
If you’re just trying to speed things up, here are the three most effective things you can do right now:
1. Clear the “Login Items”
Programs often sneak into your startup routine, slowing you down.
Go to System Settings > General > Login Items.
Remove anything you don’t need launching immediately under “Open at Login.”
Toggle off unnecessary background apps under “Allow in the Background.”
2. Run Disk Utility First Aid
This is the Mac equivalent of “tuning the engine.”
Open Disk Utility (found in Applications > Utilities).
Select Macintosh HD in the sidebar.
Click First Aid at the top and let it run. It will freeze your Mac for a minute—that’s normal!
3. Clear System Caches
If an app is acting “weird” (crashing or glitchy), its cache might be corrupted.
In Finder, press Shift + Command + G.
Type ~/Library/Caches and press Enter.
You can safely delete the folders of apps you no longer use or are currently troubleshooting.
Which one is it? Are you staring at a weird icon during startup, or is a specific app giving you a headache?
