this hasn't been solved yet despite Admin said two years ago he's look into it. And to answer his qwuestion, SAFARI Versión 10.1.2 (10603.3.8) is old, but it is also the latest version that is possible to instakll in Yosemite 10.10, which means I CAN'T INSTALL A NEWER, BETTER ONE, while miy Mini Mac would run smoothly with a newer Mac OSx either,. Yosemite runs OK AND I DON'T WANT TO CHANGE IT (nor I'd be very proficient6 in doing so). this update reply is to report that, moreover the SAFARI 10.1 issue not being resolved yet, today I've lost also the possiblity of LOGIN IN through CHROME Versión 87.0.4280.88 (Build oficial) (x86_64). the message I obtain now there is the same as SAFARI's: "COULD NOT LOAN CRITICAL FILE. PLEASE CHECK YOUR INTERNET COONECTION AND TRY AGAIN" which obviously, will not wrok, trying again, forever more. First, or prior to that message, comes this Browser's BLOCK, (which I must circunvent through an "Advanced Configuration" button below the actual message, in order to get thus rejected: " La conexión no es privada Es posible que los atacantes estén intentando robar tu información de www.bridgebase.com (por ejemplo, contraseñas, mensajes o tarjetas de crédito). Más información NET::ERR_CERT_DATE_INVALID " would it be possible, PLEASE, to finally give support to both browsers in Mac OSx 10.10? NOW I'M FORCED TO LOGIN THROUGH MOZILLA FIREFOX Version Firefox 78.9.0esr.dmg which is also quite old, fort Firefox. If I ever lose this third option, i'm gong to be in really real trouble to continue playing @ bridgebase online... thanks, Admin.
