Apple today provided the third beta of an upcoming macOS Tahoe 26.4 update to developers for testing purposes, with the update coming a week after Apple seeded the second beta.

Developers can download the macOS Tahoe 26.4 update by opening up the System Settings app, selecting the General category, and then choosing Software Update. Beta Updates will need to be enabled, and a free developer account is required.

macOS Tahoe 26.4 adds a new Charge Limit feature so Mac users can select a maximum charge level that ranges from 80 to 100 percent. Apple also brought back the Compact tab layout in Safari for those who missed the option in earlier versions of macOS Tahoe.

Apple silicon Macs who are running apps that still rely on Rosetta will see warnings about the upcoming end of support for Rosetta. After macOS Tahoe 27, Apple will phase out Rosetta support, and all apps will need to be updated before that time.

macOS Tahoe 26.4 will be released to the public in the spring after several weeks of beta testing.

it isn't yet but ipsw is


if you know how to use ipsws you can install that way

rather than wait for some bro to post full installer link you can get the link in terminal yourself by running this

Code: 
for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-26seed-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

currently it shows link for beta 2 maybe the beta 3 link coming tomorrow

or it might take longer this time. there are rumours they delayed the tahoe beta to stop leaks on info for the new macs

Who knows... but you can run this in Terminal to get back there again:
open "x-apple.systempreferences:com.apple.Software-Update-Settings.extension?action=showBetaUpdates"
