The short answer: a Mac that has turned slow usually has one of seven maintenance problems: a startup disk close to full, apps that launch at login and keep running in the background, a browser keeping every tab active, memory pressure that has moved out of green, updates installed at the wrong moment, a backup nobody has tested, or a LinkedIn automation Chrome extension running inside the browser all day. Each has a quick check, listed below with Apple's own menu paths for macOS 27 Golden Gate.
Valley is an AI outbound platform that finds the people most likely to buy from you - from live buying signals, natural-language search, or your own lists - qualifies them against your ICP, researches each one, and sends personalized messages across email and LinkedIn that get 15-45% reply rates, against a category average of about 2%.
The seven mistakes at a glance
Mistake | What you notice | Where to check | The fix |
|---|---|---|---|
1. Letting the startup disk fill up | Updates fail, large files will not open | System Settings > General > Storage | Clear what you no longer need; macOS 27 wants 35 GB free |
2. Never checking what opens at login | Slow start, fans on from the first minute | System Settings > General > Login Items & Extensions | Remove items you do not use; switch off background permission |
3. Keeping every tab awake | Browser slows, then the whole Mac does | Chrome > Settings > Performance | Turn on Memory Saver |
4. Reading free memory as the health check | Beachballs while memory looks used up | Activity Monitor > Memory | Watch memory pressure, not free RAM |
5. Updating at the worst moment | Forced restarts before calls | System Settings > General > Software Update | Set automatic updates, install on a fixed evening |
6. Assuming backups run | Nothing, until a file is gone | Time Machine settings | Add a backup disk and test a restore |
7. Running LinkedIn automation from a Chrome extension | Browser must stay open all day | Your extension list | Move sending and research to cloud-based LinkedIn automation |
The order matters. Start with the disk, because a full disk also blocks the update in mistake 5, and finish with mistake 7, which takes the most work off the machine. Most of the checks below take Apple's own menu paths; the strategies to boost sales productivity cover the rest of the working day.

Give your sales team
an unfair advantage.
1. Letting the startup disk fill up
Sales machines collect exports, call recordings, screenshots of replies and old installers for months. Nothing warns you until the disk is nearly full, and by then updates fail and large files stop opening.
Check: Apple menu > System Settings > General > Storage, then wait for the bar to finish loading. Apple's storage guide lists three built-in recommendations there: Store in iCloud (Desktop and Documents move to iCloud Drive), Optimize Storage, and Empty Trash Automatically, which erases items that have been in the Trash for more than 30 days.
Fix: if you are already seeing a not-enough-disk-space warning, MacPaw's fixes in this guide go step by step: checking storage, removing large old files, deleting old iPhone and iPad backups in Finder, uninstalling unused apps and the leftover files they keep in your Library folders. MacPaw puts the macOS 27 Golden Gate installer at 18 GB and recommends at least 35 GB free before upgrading.
2. Never checking what opens at login
Every video tool, sync client and helper app you have ever installed may have added itself to startup. Each one takes memory before you open a single tab.
Check: Apple menu > System Settings > General > Login Items & Extensions. Apple's login items guide lists the apps that open when you log in, and gives each app an Allow in the Background switch that lets it check for updates or sync data while it is not open.
Fix: select anything you do not use daily and click the Remove button below the list. Then switch off Allow in the Background for apps that have no reason to work while closed.
3. Keeping every tab awake
A sales day runs in the browser: LinkedIn, the CRM, the inbox, a sequencer, a calendar, the other sales productivity tools and research tabs. Left alone, all of them stay active and compete for memory.
Check and fix: in Chrome, open the three-dot menu > Settings > Performance and turn on Memory Saver. Per Google, Chrome then deactivates tabs you are not using and reloads them when you return. There are three modes: Moderate, Balanced (the recommended one) and Maximum, which deactivates tabs soonest. Tabs that are playing audio or video, sharing a screen, holding a half-filled form or pinned stay active, and you can add sites such as your CRM to an always-active list.
4. Reading free memory as the health check
A Mac that shows almost no free memory is not necessarily struggling. Apple's own guide notes that unused memory does not necessarily improve performance.
Check: open Activity Monitor and choose the Memory tab. Read the memory pressure graph at the bottom. Per Apple, green means the Mac is using its RAM efficiently, yellow means it might eventually need more, and red means it needs more RAM. Next to it, Swap Used is how much of the startup disk macOS is using to move data in and out of memory, which is one more reason the disk in mistake 1 matters.
Fix: sort the process list by memory and quit what sits at the top without a reason to be there. If pressure stays red with only your normal work open, that is a hardware limit, covered further down.
5. Updating at the worst moment
Updates carry the fixes, but an update that installs itself on the morning of a demo costs more than it saves.
Check and fix: Apple menu > System Settings > General > Software Update. Apple's update page lets you choose whether updates download or install automatically. Let them download automatically, then install on a fixed evening each week, after clearing the disk space from mistake 1.
6. Assuming backups run
A backup that has never been tested is a guess. It matters on a sales laptop because the files that live only there, such as call notes, exports and proposal drafts, are the ones nobody else has a copy of.
Check and fix: click the Time Machine icon in the menu bar and choose Open Time Machine Settings, then Add Backup Disk. Per Apple, Time Machine makes hourly, daily and weekly backups to an external disk, a network disk or a Time Capsule. Once a month, restore one file to prove it works.
7. Running LinkedIn automation from a Chrome extension
A LinkedIn automation Chrome extension only works while the browser is open, adds its own work to every page it runs on, and sends from your own connection. That ties the whole outreach motion to the state of one laptop: close the lid and it stops; a slow afternoon becomes a slow campaign.
Fix: move the finding, research and sending to cloud-based LinkedIn automation, so the laptop only shows results and replies. Valley works that way: it runs outreach in the cloud on dedicated IPs, watches buying signals such as profile views, post engagement, hiring and funding, qualifies each person against your ICP and drafts a personalized message in your voice. You approve every message from one tab, or let them flow. Across 1,000+ connected LinkedIn accounts, there have been zero suspensions; Valley's safety features explains how. For the account-risk side of extensions, see LinkedIn automation safety in 2026, and for cutting the tool count, how to simplify a LinkedIn outbound tech stack.
Once the laptop stops being the bottleneck, the message decides whether anyone replies.

Memory pressure stays red with only your usual apps open. The Mac needs more RAM. Apple's guide shows how to check: hold Option, open the Apple menu, choose System Information, then Memory. If no Memory Slots pane appears, the memory cannot be upgraded, and the option left is a Mac with more of it.
Your Mac uses an Intel chip. MacPaw notes that macOS 27 Golden Gate supports Apple silicon only (M1 or later), so an Intel Mac will not be offered the update.
One app is always at the top of Activity Monitor. That is an app problem, not a maintenance one. Update or reinstall that app before changing anything else.

FAQ
Why is my Mac so slow all of a sudden? The most common causes are a nearly full startup disk, a new app that added itself to login items, or a browser with many active tabs. Check Storage, then Login Items & Extensions, then Activity Monitor's memory pressure, in that order.
How to check storage on a Mac? Open the Apple menu > System Settings > General > Storage and wait for the bar to load. The same screen shows Apple's recommendations for freeing space.
How to stop apps opening at startup on a Mac? Go to System Settings > General > Login Items & Extensions, select the app and click the Remove button below the list. Each app's Allow in the Background switch is on the same screen.
How much free space does macOS 27 Golden Gate need? MacPaw puts the installer at 18 GB and recommends at least 35 GB free before upgrading. It also runs only on Apple silicon Macs.
Does closing browser tabs speed up a Mac? It can, because open tabs hold memory. In Chrome, Memory Saver deactivates tabs you are not using and reloads them when you return, so you do not have to close them.
What does yellow memory pressure mean on a Mac? Apple says yellow means the Mac might eventually need more RAM. Quit what you are not using first; if pressure turns red during normal work, the Mac needs more memory.
Is a LinkedIn automation Chrome extension or a cloud-based tool better? For the laptop, cloud-based. An extension only works while the browser is open and sends from your own connection. Cloud-based LinkedIn automation such as Valley runs the work on dedicated IPs, so the laptop only handles replies.
