Why Is My Mac's Internet so Slow?
Today's Mac computers running macOS and any other devices for that matter are very much dependent on the internet to work properly. Whether it's updates or apps that sync online, you need a fast and stable connection.
But when is your macOS Internet slow? First – run a speed test to confirm this:
- If you get slow Internet connection on your macOS device only, you may just have to reboot the device. Or you may need to perform an antivirus scan to check that everything is fine.
- If the slow Internet connection appears on multiple devices, then it’s almost certainly a network problem.
When you have macOS Internet slow issues on your Mac, you'll notice that apps lag too, as they wait to sync online. The reasons for such problems include, but are not limited to:
- poor connection in rural or remote areas;
- temporary ISP infrastructure issues;
- router or modem issues - outdated firmware, needing a restart, etc.
- you're too far from the Wi-Fi router / hotspot.
The signs of macOS slow internet are ever so green, unfortunately. Just to name a few:
- websites / apps take forever to load or refresh;
- videos are buffering;
- you experience stuttering and buffering when video conferencing;
- downloads / uploads are slow.
How to Fix Slow Internet Problems on macOS: Use All Available Connections at the Same Time
As mentioned above, we are not going to explain how you can troubleshoot a slow Internet connection on your Mac. Instead, we are going to focus on getting that fast and stable connectivity you've always wanted, in a matter of minutes. All you need is Speedify fast bonding VPN.
Speedify allows you to use all of your available connections at once on your macOS device. Remember - that's "at once" and not "switching between them" - here's the difference.
Speedify dynamically sends traffic through all your networks that are connected on your Mac - Wi-Fi, wired Ethernet, cellular, etc. Depending on each network's performance, you get the fastest, most stable and secure Internet at any given time. If one of the connections drops (e.g. you connect to a sticky Wi-Fi hotspot), Speedify will move more traffic over cellular or wired Ethernet. And it's all seamless to you, even when streaming - you won't even know it happened till you check the stats in the app.
How to use Speedify on macOS
- Get it from the Apple macOS Store or our website.
- Use the integrated Wi-Fi and wired Ethernet adapters and also connect external network adapters on your MacBook, iMac, Mac Pro, Mac mini, etc. via the USB ports. This will help you to connect to multiple networks.
- Run Speedify - it will automatically recognize each new connection and start using it.
You can find more details about combining different connections types in our knowledge base.
Forget about macOS Slow Internet Issues - Speedify Provides Fast, Stable and Secure Connectivity
Aside from getting you fast and stable Internet connectivity, Speedify uses servers in the cloud and encrypts your traffic to and from those servers. This means that your online activity is safe from hackers and cyber criminals that might be lurking on public Wi-Fi networks for example.
This comes in handy also when the network you're connected to restricts access to certain websites and apps - mostly streaming and social media ones - YouTube, Facebook, TikTok, etc. This is the case for many educational and office networks. The point is that with the traffic being encrypted, you can access those websites freely.
There's another upside to this: you can choose the servers to connect to, including those in other countries. So, if you're abroad or need to access a local resource within a country, connect to a server in the region where access is not blocked and you're all set!
To wrap this up: using Speedify on your macOS device will fix any slow Internet issues and provide peace of mind when using the Internet.
