Scenario
Downloading the Microsoft Office installation software from the internet to a Mac computer.
Observed behavior
The download process is extremely slow, takes several hours to complete, or stalls completely due to poor Wi-Fi performance.

Switch to a Wired Ethernet Connection

Using a stable wired network connection instead of Wi-Fi is the most effective way to improve download reliability and speed for large files.

Wi-Fi connections can suffer from interference, distance limitations, and packet loss, which severely throttle the download speeds of large installation packages. A direct Ethernet connection provides maximum available bandwidth and a stable link to the Microsoft servers.

1
Connect an Ethernet cable

Plug an Ethernet cable directly from your router into your Mac. If your Mac does not have a built-in Ethernet port, use a compatible USB-C or Thunderbolt to Ethernet adapter.

2
Turn off Wi-Fi

Click the Wi-Fi icon in the Mac menu bar at the top right of your screen and toggle it off to force macOS to route all traffic through the wired connection.

3
Pause and resume the download

Open your browser's download manager, pause the current Microsoft Office download, and then click resume to establish a fresh connection over your new, faster network.

Switch to a Wired Ethernet Connection
Connection Stability: A wired connection drastically reduces the chances of the download timing out or becoming corrupted mid-transfer.

Frequently Asked Questions

Why does my Microsoft 365 download get stuck at a specific percentage on my Mac?

Downloads usually get stuck when there is a brief interruption in your Wi-Fi signal or if the Microsoft servers experience a timeout. Pausing the download in your browser and resuming it after a few seconds is often enough to force it to continue.

How large is the Microsoft Office installer file for macOS?

The standalone offline installer for Microsoft Office on Mac is typically between 2 GB and 3 GB. Because it is a large file, slower internet connections may take several hours to complete the download.

Can I download the Mac Office installer on a different computer?

Yes. If your Mac's Wi-Fi is too slow, you can download the macOS offline installer (.pkg file) on another computer with a faster internet connection. Once downloaded, copy the file to a USB flash drive and transfer it to your Mac to run the installation.

Does my Mac's firewall or antivirus slow down file downloads?

Occasionally, strict third-party antivirus software or network firewalls scan incoming packets aggressively, which can throttle your download speeds. Temporarily disabling these security features while you download the file can improve speeds, but remember to re-enable them once finished.
