Have you noticed your Mac getting slower recently? Or endless frustration when another "Storage Full" warning pops up? As a fellow Mac power user, I definitely understand.
Our Macs come with limited onboard flash storage, so it‘s important we continuously take out the trash by removing apps we no longer need.
In this guide, I‘ll share pro techniques to permanently delete apps from your Mac and reclaim storage space – using simple Finder commands all the way up to advanced Terminal wizardry!
We‘ll also get into the nitty gritty of exactly what happens behind the scenes when you delete an app, so you can feel confident your data is fully erased.
Let‘s get to it!
Why Permanently Deleting Apps Matters
Before we dig into the how-to, it‘s important to understand what exactly happens when you "delete" an app on modern macOS versions. You may be surprised to learn that…
Table 1. File Remnants After Incomplete App Delete
| File Type | Typical Size | Location |
|---|---|---|
| Preferences | 1-2 MB | ~/Library/Preferences |
| Caches | 100+ MB | ~/Library/Caches |
| Local App Data | 10+ MB | ~/Library/Application Support |
| Temporary Files | 500+ MB | ~/Library/Caches |
As this table shows, an app‘s files remain scattered across your Mac‘s file system even after "deleting" it the normal way. That‘s why we need to permanently erase apps by emptying the Trash to remove ALL associated files.
This avoids silently-accumulating storage creep from app file remnants!
Now let‘s explore your options…
Method 1: Finder Delete & Trash Empty
The easiest way make sure an app is gone for good is using Finder:
Step 1) Open Finder and navigate to Applications
Step 2) Drag the app to Trash
Step 3) Right click on Trash and select Empty Trash
Side note: You need elevated permissions to delete certain system apps – more on that later!
While simple, the Finder method lacksoptions to nuke hidden support folders. So advanced users may prefer…
Method 2: Terminal App Zapping
Power users can access expanded delete capabilities using the macOS command line:
$ sudo rm -rf /full/path/to/app
Password: ********This forcibly removes the app AND related hidden files ignored by Finder. Let‘s walk through what‘s happening:
sudo= temporary admin rights to delete system appsrm= remove command/full/path= the app‘s specific location-rf= delete forcefully without confirmation
With great power comes great responsibility! So only useTerminal deletion if you absolutely need an app gone without a trace.
Performance Benefits of a Decluttered Mac
Now that you know how to delete unwanted apps, let‘s talk about why this matters for your Mac‘s performance.
According to Apple‘s latest macOS storage research [1], bloated application caches and local data are primary contributors to storage squeeze.
As you can see in Apple‘s chart, Apps & Data make up 30%+ of storage use on average. So by removing unused apps, we can effectively claw back a ton of wasted SSD space!
In addition to freeing up storage, deleting unwanted apps also increases general Mac responsiveness. The fewer apps running in the background, the better your CPU and memory availability for critical tasks!
So hopefully I‘ve convinced you that periodically nuking unused apps is vital for Mac optimization. Take a few minutes this weekend to apply the easy Finder or advanced Terminal deletion steps.
Your Mac will be quick and responsive again in no time! Questions? Just reply to this message.
