EyeTV compatibility with newer iMac models for broadcast TV recording

According to some of the posting in link below

Specifically >>. EyeTV 4.0.0 (8532) works fine and no issues with MacOS 15.2 (24C101) on an Apple Mac Mini M2 Pro with the "EyeTV Hybrid" USB stick (ATSC, not DVB). I am using a high-performance external Thunderbolt disk for both my EyeTV archive and also other video recordings. 

Using a Mac Mini Pro with Apple Silicon works

Though, purchasing one of there machines Now would probably mean it would come with macOS 26 Tahoe

The latest and greatest offering from Apple

To get the 27 " Display we seniors may need

You do not have to purchase Apple Displays link those listed in below link ( a pretty penny I dare say )

Purchase a 27 " or larger Display of your choice

I am using the M4 Mac Mini ( 16 GB Unified RAM/ 500 GB SSD ) with an older 27 " Asus VP 278 Display on Tahoe 26.0.1 and work just fine in general usages

Displays

Part 2 and specifically regarding the update from " iMac (Retina 5K, 27-inch, 2019) with Sequoia 15.4. " and " if I want to update "tonight" or "later," it fails to install the update. "

There are factors:

Some which are beyond your control and those which are totally under your control

Like poor Wifi connection

Slow wifi connection

Too many other people downloading at the same time and Apple  Servers are overloaded

Software on the computer interfering with the download process including AntiVirus Software

Notation: Disabling the AV Software may or may not solve the issue. Removal of the AV Software may increase the chances of the download to perform as expected.

Running behind a VPN which may increase Packet losses or corruption of the download 

Turn off any Third Party Two Way Firewall and try again 

If via wifi  & too many Other devices using the wifi at the same time reducing the Bandwidth to your computer. 

Best Results are via Ethernet Cable to Router

Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal 

Try Again using the Software Update Applet in System Preferences / Setting 

Worst case - Restart in Recovery Mode and choose Reinstall macOS. 

This in theory will pull the latest version of macOS this computer qualifies to run

Owl-53, one of the "MacOS gurus" on this site, has great suggestions.

One thing you can do is: (1) restart the Mac and make sure nothing is running except the Finder; (2) then go to Software Update and instruct it to update immediately (sometimes this is through a restart now button or other similar button). Before doing that, check the Applications folder for a previous downloaded MacOS installer and remove it and empty the trash if you find one there. When you tell it to update now, at that point, the Mac should restart start to do the update.

[Caveat: if you haven't updated in a while, you might be surprised at how many times the Mac restarts in the process. By patient. The screen also goes blank several times, and the computer can appear to be "dead," but it is in fact very alive and when its screen is blank or black like that, it is most likely updating the firmware. That is a crucial step and it can look blank/black for 60 seconds or more, but it is key to just leave it alone. 60 seconds is a long time when one is watching. I have a philosophy: "a watched update never seems to complete," and "a watched backup never seem to finish." So best to leave the room for at least 30 minutes, maybe an hour or more, and leave it alone to do what it needs to do. Also, these updates take longer on older machines. The last 15.7.1 update I did on an M3 Mac took < 15 minutes but it took ~ 45 minutes on my 2019 Intel MacBook Pro.]

I assume this is Apple's way of saying your machine is too old, so "buy up" if you want to continue using your Apple products.

I don't think that is the case. In fact your 2019 iMac should be able to run the latest version of the OS, Tahoe, as can my 2019 MacBook Pro 16". They are supported and it should work, but it is good to check compatibility of the newer MacOS with things you have installed or connected before upgrading.

Apple has no need to nudge owners of older Macs to upgrade. Most of Apple's profit comes from iPhones anyway, not from desktop Macs. And there are not that many people still using 6-yr old Macs. The company I work with mandates replenishment of all desktop and laptop computers every three years.

@steve626

You make me blush.

Thank you for chipping in here

Very interesting. But this is strictly UK/European TV only, correct? America is ATSC, which I don't find listed in the specs for the eyeTV products.

Have you tried the EyeTV forum?
