Notes from the workshop
How the Mac works under the hood, what the apps do and why they do it that way, and how the studio ships software. Written by the people who build them.

What a Mac cleaner should never do
Most cleaning apps ask you to trust them. SweepyMac is built so you do not have to: everything it removes goes to the Trash, every clean has an Undo, and every group opens up before you press anything.

Smart Scan or Cleanup? What one click cleans, and what it deliberately leaves alone
SweepyMac has a one-click scan and a full Cleanup module, and they are not the same thing. Here is exactly what each one touches, which categories start unticked and why, and the folders neither will ever offer you.

Full Disk Access: what you are actually granting, and why SweepyMac asks once
The macOS prompt everyone clicks through. What Full Disk Access unlocks, what it does not, how to check which apps have it, and why a scanner is one of the few tools that has a real case for it.

The Mac Health score, explained: every number, every threshold
SweepyMac sums up your Mac as one score out of 100. This is what goes into it, exactly when each recommendation fires, and why a check that cannot read its data is skipped rather than marked fine.

Getting disk space back from iCloud Drive without deleting a single file
Files you downloaded from iCloud Drive keep a local copy on your Mac. Evicting that copy frees the space, keeps the file in iCloud, and leaves it one click from coming back. Here is how it works and when it is worth doing.

Clearing browser data on a Mac: what a cleaner can touch, and why Safari is different
Cache, history and cookies for every profile of every browser, listed one row at a time and nothing pre-selected. How SweepyMac's privacy cleaner works, why Safari only offers its cache, and why you must quit the browser first.

How FocusLens tracks your day without asking for a single permission
No Screen Time API, no Accessibility access, no browser extension. FocusLens listens for the same app-activation notifications the Dock does, and that turns out to be enough to build a complete picture of where your attention went.

What SweepyMac's malware scanner actually checks, and what it is not
Launch agents by name, file contents by hash and byte pattern, code signatures, cron jobs and browser extensions. What each signal means, why a finding is labelled by how it was found, and why an on-demand scanner is a complement to macOS, not a replacement for it.

The twenty-three minute cost of a context switch, and how FocusLens counts it
Switching apps is free. Getting your head back into the work you left is not. FocusLens prices the disruptive switches at the figure interruption research gives, names the apps responsible, and groups the rapid-fire bursts so you can see them.

Uninstalling a Mac app completely: the eleven places it leaves things behind
Dragging an app to the Trash removes the app and nothing else. Its preferences, caches, containers and launch agents stay. Here is where they live, how SweepyMac finds them, and why some apps need a password to remove.

Why our apps make no network requests, and the one exception
FocusLens has no network code at all. SweepyMac has one connection, for a signed malware definitions file. Here is what no telemetry means in practice, what we give up for it, and how you can check the claim yourself.

What starts when you log in, and the three chores you used to need Terminal for
SweepyMac's Performance module lists your login items with a Disable button, shows the system agents macOS manages, and runs three maintenance tasks with one click. How the background helper makes that silent, and why it needs a signed build.
