Setup guide
UHF on your iMac, step by step
Short version: install UHF, sign in with your Ultra 8K IPTV details, and let it load. The steps below cover the parts specific to the iMac, from where to find the app to the settings that keep 4K feeds smooth.
- No contract
- 7-day refund
- Login in ~60s

UHF is free to download. On a phone or laptop screen, HD feeds already look sharp; 4K only pays off on a 4K display. If it doesn't suit you, the 7-day money-back guarantee applies, and because plans are prepaid there's nothing to cancel later.
Prep, in four lines
- Your login from WhatsApp: server URL (with port), username and password
- Permission to open apps from identified developers, if the app comes from its own site
- A 25 Mbps line handles one 4K stream comfortably; HD needs roughly 10 Mbps per screen
The setup, in order
- Order on WhatsApp from the buy page. Your login details come back in the same chat, usually within a minute.
- Get UHF from the Mac App Store or the developer's own site; if it arrives as a download, drag it into Applications.
- Select Add user or Add playlist in UHF, choose Xtream Codes, and fill in the three fields from your login message: server URL with its port, username, password.
- Wait for the first load to finish, open a channel to test it, and star the ones you watch most.
The first time you open it
Expect a short wait on first sign-in while UHF downloads the playlist and guide. Then you'll see channel groups by category and country; open one, highlight a channel, and the guide shows what's on now and next.
Troubleshooting
- "Invalid credentials": retype the server URL with http:// and the port, and check capital letters; the username and password are case-sensitive.
- Channels but no guide: refresh the EPG in UHF's settings, or give it a few minutes after the first sign-in.
- Buffering on sports only: run a speed test on the iMac. Below about 25 Mbps, use the HD version of the channel.
- Guide off by an hour or more: check the iMac's time zone first, then the EPG offset in UHF.
Tune it for the iMac
- Keep VLC installed as a backup player for testing the stream.
- Connect to a TV over HDMI for a bigger picture with the same app.
- Turn on hardware acceleration in the player settings.
- Guide refresh: set the EPG to update daily so listings never run out.
