Apple Releases Second macOS Tahoe 26.4 Public Beta

I get the same error. Tried multiple times. Mac Studio M2 Ultra. Not sure what to do.

Same problem, but so far no solution.

Same problem, but so far no solution.

ota download isn’t the only way to install the beta. it’s probably the way most people do it because it is the quickest.

there are other ways:

- ipsw file

- full installer

- bootable usb of full installer

have you tried these ways?

Some rose-colored glasses there. SL had its issues early-on.
🙂

But seemed to be hammered out at the end.
Though not perfect of course, it was very stable at the end.

I haven’t, but since everything I’m using is working with beta 1, I think I just might wait for beta 3 and see what happens. If there are still problems with updating, I’ll try the full installer.

Just say No to this beta, especially if it's your daily driver. If you are having trouble installing, you are lucky, it's the "universe" trying to tell you not to. 🙅

I think you may be right!

I easily found the IPSW file, but where is the full installer available?

most recent tahoe public beta full installer link will be revealed in terminal if you run

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-26beta-1.sucatalog | grep com_apple_MobileAsset_MacSoftwareUpdate.plist | grep -Evw '(com_apple_MobileAsset_MacSoftwareUpdate.plist.integrityDataV1)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
curl -s $file | egrep -A 1 -m 2 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
echo $file | sed -e "s/com_apple_MobileAsset_MacSoftwareUpdate.plist/InstallAssistant.pkg/g"
done

this is more useful than just giving you a link to a particular beta because you can use the same code to get future betas too.

YEAH!!! Getting the compact tab back! Even if I am only one of the 10% who use it, thanks, Apple, for listening to the minority who really like that feature.

Downloading the entire installer worked, and I updated to Beta 2. All works fine.

Something funny is going on with Beta 2.

I connect to my NAS via Thunderbolt - treating the NAS as a DAS. The connection is made using SMB. The NAS is a QNAP, and generally my transfer rates from Mac Studio to NAS is really really fast, as in faster than using 10GbE.

After the Beta 2 update, transfer rates to NAS are super slow. It literally took minutes to transfer just a 300mb file. Something that usually takes less than a second. I changed to connect via 10GbE, as well as normal Gigabit network, and all is slow.

Anyone else with SMB issues? Or is this an issme... I haven't changed a thing on the NAS, so I am inclined to believe it is a macOS issue.

Is this update still having issues? I have an M1 MBA.

IMO - Beta 2 doesn’t have problems, it was the updater itself. If you get the dreaded “Failed to prepare the software update. Please try again”-error, follow the instructions above, grab the full installer and run that. It works!
