Oct 13, 2019 I downloaded Canon Printer software in order to set up the Wi-Fi connection, but I get “mac-ts8200-11-mcd.dmg” is damaged and can’t be opened. You should move it to the Bin.” message when I want to open it??? Catalina refuses to open any.dmg &.pdf files. Also some difficulties with opening some apps. This must be a bug in Catalina!!! Nov 29, 2018 MatterHackers has just released MatterControl 2.0, the latest version of its free all-in-one software that allows users to design, organize, slice, and print their 3D models from one platform. If you can’t open Safari or a new Safari window, try these suggestions. Make sure you’re using the latest versions of Safari and macOS. To check for a Safari or a macOS update, choose Apple menu App Store, then click Updates. If you are having a problem with MatterControl that is not fixed by re-installing, you may need to delete some of the data that MatterControl saves on your computer. This data will persist, even if MatterControl is uninstalled so remove that folder if you want to completely reset MatterControl to a clean slate. Open a new Finder Window; Navigate to the Download or Application you just installed to your Mac; Instead of Double-Clicking on the Icon to open, Right Click on it and choose 'Open' A Pop-Up Window will appear telling you that the Software is from an Unidentified Developer, but it will give you the option to Open.

Hi everyone--
I have a Macbook Pro 3,1 Intel Core 2 Duo 2.4ghz running 10.6.8
All software is up to date, including the security update from about a week ago.
So now when I log into my account, it lets me open any applications, so I open up say, safari and mail.
Then after working on those apps for like 5 minutes, I can't open any other applications, like they just bounce once then won't open. And then, if I close safari or mail, then they won't reopen until I log out then in again.
I've gotten accustomed to just opening all the apps I'm gonna need right when I log in, but I'd really like to fix this..
Any ideas?
Macos close app when closing window swift.
Thanks,
Ben
