I’d first update to 26.7.1, and then upgrade to 27.0.1. See if that works better.

Have you checked if 'Low-Data Mode' within 'Details' in 'Wi-Fi' in System Settings is turned off.

it's helpful, because yesterday when appeared to download macOS27.0.1 did the process to the end and appeared an advertisement for 5 minutes more and stayed during 2 Hours and the process had to be aborde, so ouldn't download it.

Nos, i'm doing the download of macOS Tahoe 26.7.1 and new still awaiting for those 5 minutes more to end and nothing finished.

as I am at Argentina, can you explain what is Low Data Mode? or if it's possible you can reply me in Spanish


no updates appear after general; buscar actualizaciones, no reply

Kind Regards, from Argentina
