I have an old iMac running OSX 10.7.5/Safari 6.1.6.
Due to some programs on that system & generally slow systems on similar iMacs with more recent OSX version I do not want to update to a newer OSX
I have several websites forcing https which I can no longer access as safari says "Safari can not open the page …, as safari can not establish a secure connection to …" (translated from german).
Chrome and Firefox on the same machine are able to open these pages, as are more recent Safaris on more recent machines.
I tried downloading/installing the root certificate in the keychain, but this did not help.
Are there some security updates I'm not getting via normal system updates which could fix this?
For example: www.biblio.lu
