Introducing Simon 5!

Simon version 5 is now available. It is a massive update, introducing a much-requested feature: syncing the Simon data between multiple Macs, plus a Simon Status service, a Link Checker filter, improved Find filter, iMessage and Speak Error notifiers, a new app icon, and much more.

Important: please note that Simon 5 requires a minimum of macOS 10.12 (Sierra), and is a paid upgrade from Simon 4. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).

Read the Simon What's New page for details.

update to Simon 2.5.3

how to do please ?

the DL link go to ""

but the file inside is an 2.5.2

also it could be nice to remove the number of failures on the menu icon when we do "Mark all read" like in a email app.

thank's for your help

Re: update to Simon 2.5.3

Try downloading again. There was a problem with the initial upload, but it was quickly fixed. Perhaps you downloaded an earlier edition?

The number on the Dock icon indicates the number of tests with the most important status (failed, changed, or recovered, in that order). You can disable it entirely if you prefer, via the preferences. I'm not sure it'd make sense to remove the number when marking as viewed, though... but I welcome discussion on the idea.
