How to make YouTube faster on Mac: The quick guide

If you see that a short 2-minute video takes forever to download, it’s probably because YouTube is slow on your Mac for one of the following reasons: 

• Slow network
• Intrusive ads
• Website glitching
• Mac’s disk permissions and more.

Whatever the reason, I’m here to help you and share the practical steps and tools I use to speed up YouTube on Mac, so you can get back to easy streaming without the headaches.

Quick ways to speed up YouTube

If YouTube feels slow on your Mac and you’re looking for a quick solution, try one of these proven fixes I collected in the guide that are among the most common:

What’s the issue?	Quick fix
Slow or spotty Wi-Fi	Map your signal with NetSpot to find dead zones
Browser cache and extensions	Clear site data in Safari; use CleanMyMac for a deeper cleanup
Intrusive ads slowing playback	Install AdBlock in your browser
Disk permission errors	Run First Aid in Disk Utility or use CleanMyMac
Background apps hogging bandwidth	Use TripMode to restrict internet access by app (my most used fix)
Low available RAM	Close unused apps; lower YouTube quality to 720p

The table is easy to catch on to, but if you want to dig deeper into each method, I prepared each solution with details below.

Check your internet connection

Checking your internet connection is an obvious first step, but many people overlook it when troubleshooting slow YouTube performance. 

I recommend you start with the following:

• Test your speed: The FCC (Federal Communications Commission) recommends at least 15 Mbps for HD streaming. You can use Speedtest.net to check your bandwidth, but for me, the results feel inconsistent.
• Optimize network usage: If you’re on a shared Wi-Fi, ask others to pause heavy downloads or streaming during your session (works for any internet activity, though).
• Map your Wi-Fi: For a more reliable approach, try NetSpot (Wi-Fi analyzer). It scans your Wi-Fi coverage and performance. And it detects the best access points and shows signal strength through heat maps, so you can find the optimal spot for fast connections.
• Troubleshoot dead zones: NetSpot also helps you troubleshoot dead zones and optimize your setup with live scans and real-time speed checks.

But before you dive into network tweaks, make sure the issue isn’t on YouTube’s end. A quick glance at Downdetector can show if there’s a widespread outage affecting YouTube services.

Block ads

Ads are not only irritating but also can be a root problem of why YouTube is slow on your Mac. All because they disrupt streaming algorithms and make YouTube run slowly. So, blocking ads is a quick solution.

To block ads and pop-ups:

• Use a browser extension: AdBlock for Safari or Chrome can block most YouTube ads. As an alternative, use AdLock (works in any browser on Mac and iPhone). AdLock blocks ads and trackers system-wide, across every browser and app — so YouTube loads the video, not the ad. Try AdLock Free. Or get AdLock standalone via Marketplace — $4.99/mo, no membership needed.

• Remove distracting plug-ins and malware: Use CleanMyMac (Mac system optimization app) to remove unwanted browser extensions and plug-ins. Open CleanMyMac and run the Performance and Protection modules.

• Extra tip: Clearing your browser cache and cookies can also resolve slow video playback. In Safari, go to Safari > Settings > Privacy > Manage Website Data and remove YouTube data.

If you want to remove ads from your daily web routine, I recommend checking the list of top ad blocker apps for Mac.

Use an external player

Instead of streaming the traditional way through the YouTube website, using external players can be an effective and easy way to speed up your videos. This eliminates the influence of ads and pop-ups without having to download blockers, which may use more data on your Mac than you want.

Try these tools:

• VLC Media Player allows you to play YouTube videos by pasting the video URL into the app.
• IINA is a modern macOS player with YouTube integration.
• Extra tip: Use Downie or Pulltube to download videos from YouTube on your Mac. Both support drag-and-drop, and you can download videos not just from YouTube but from other websites as well (e.g., Facebook, Vimeo, Instagram, etc.). If you prefer downloading with subtitles, pick Downie. If you want extra editing features, like trimming or audio extraction, choose Pulltube. And both apps let you download videos in high res, like 4k, 8k, HD, and more.

If you're not sure which app — Downie or Pulltube — fits your workflow, this video downloader assistant can walk you through it based on what you actually need to download.

Repair disk permissions

Hard-drive issues can also impact your video streaming speeds because your drive is still involved in reading, writing, or buffering video data. But there’s a simple hack for running checks and fixing disk permission glitches, which you can do right now:

1. Open Spotlight and search for Disk Utility.
2. Select your main drive and click First Aid to check and repair errors. For more details, check Apple’s official guide.

As an easier alternative, I prefer to repair disk permissions with CleanMyMac. You don’t have to pick between drives, as the app knows what to scan. To do so: 

1. Choose Performance > Scan.
2. After the scan ends, click View All Tasks.
3. In the Maintenance tab, select Repair Disk Permissions > Run.

This declutters your disk and can fix glitches that slow down YouTube.

Save data

Saving available RAM is another way to improve YouTube streaming performance. As a video streams, your computer needs somewhere to save the data, which is normally in the Random-Access Memory (RAM). This is a location external to the hard drive, meaning the video isn’t actually downloaded on your Mac.

Here’s what you can do to save data:

• Check RAM usage: Open Activity Monitor (Applications > Utilities) and check your available memory. If it’s consistently under 100 MB, consider freeing up RAM or closing unused apps.

Limit background data: TripMode (data management app) lets you control which apps can access the internet. Install and enable TripMode in your menu bar, and allow only YouTube or your browser to use data while streaming. This prioritizes bandwidth for YouTube and can noticeably improve performance.

• Track data usage: TripMode also allows you to keep track of your data usage, checking the general data used or the detailed data for any particular webpage, session, day, or required period. This enables you to detect which apps are data-hungry and disable them when you don’t need them.
• Extra tip: You can also manually lower YouTube’s video quality. Click the gear icon on any video, then choose Quality and select 720p or 480p. Lower resolutions require less bandwidth and are less likely to buffer on slow connections.
