Unfortunately the Release Notes don't note anything about the MAIL.app Issue as being resolved...
PSA: Apple Mail Bugs Can Lead to Data Loss in macOS Catalina
Is there url to download the 10.15.1 update? As well as 10.14.6 Security 2019-001?
Anyone else having issues downloading 10.15.1 from the App Store or using installinstallmacos.py?
@stutz Not that it helps identify your failure, but I just successfully downloaded the 10.15.1 installer using installinstallmacos.py. (I'm using the September 27th version of the script)
We still have problems mit Jamf and Catalina. So after fresh install via internet recovery and controlled profiles with Jamf, the only thing that works, is the Wifi Profil and the Jamf Servicepage app. We miss the jamf verify and jamf connect on the clients, file vault activation is prompted after first lockout, but after password and restart, there is still no file vault active.
And last but not least, no applications where rolled out in Catalina. With Mojave all works fine...
Does someone have a solution. We are using jamfcloud
installinstallmacos.py version is 9/27.
I get the following error:
installer: The install failed (The Installer could not install the software because there was no software found to install.)
Command '[u'/usr/sbin/installer', u'-pkg', u'./content/downloads/61/56/041-83630-A_8RCIBB415Y/7jqh3nh97ood2mjej7hdgpx7fgh5c3fi9g/041-83630.English.dist', u'-target', '/private/tmp/dmg.866P5N']' returned non-zero exit status 1
Product installation failed.
When I use the App Store I get:

The weird thing is it's happening on different machines connected to different networks.
@stutz Are your devices pointing at an internal software update server?
Why are you all want to upgrade to Catalina (?)
especially with the MAIL.app Bug still present in 10.15.1
that loses Data when Exchange + IMAP Accounts are being used...
Has anyone seen an issue with password requirement help popup displaying requirements in different language?
We have this issue, several password requirements are pushed via Jamf Policy (Passcode payload); when changing the password, and not meeting the criteria, criteria are displayed in (most probably) Hebrew (which unfortunately is useless for us, system language being English or Swedish).
Tested this on Mojave, Catalina 10.15.0 => no problem; only Catalina 10.15.1.
