I AM A LOW VISION MAC PRO OWNER WHO WOULD LIKE TO USE SONAR/ HOW USER-FRIENDLY  WILL SONAR BE 4 ME? ANY SUGGESTIONS LIKE WHICH VERSION I SHOULD START WITH? PLEASE EXCUSE ALL CAPITAL LETTERS I AM NOT SHOUTING. THANKING YOU IN ADVANCE WIL

I would say try the demo, but it's still not available.

there is no mac version of sonar BTW
 
(maybe this should be moved to the Sonar forum??? ... it's not really a feature request)

Moved to SONAR forum, not a feature request.

AS WAS MENTIONED, THERE IS NO SONAR FOR MAC. THAT MEANS YOU WOULD FIRST NEED TO USE BOOTCAMP AND INSTALL WINDOWS ON YOUR COMPUTER AND GET USED TO A NEW OPERATING SYSTEM. WHILE SOME PEOPLE HAVE DONE THIS AND ARE HAPPY WITH, IT DOESN'T SEEM THE MOST LOGICAL ROUTE FOR SOMEONE WITH VISION PROBLEMS. SO I WOULD SAY SONAR IS PROBABLY NOT A GREAT CHOICE FOR YOU. HAVE YOU USED ANY SOFTWARE LIKE THIS BEFORE? IF NOT, YOU CAN START WHICH GARAGEBAND. IF YOU HAVE, CONSIDER LOGIC, WHICH IS ALMOST UNBEATABLE IN TERMS OF VALUE IF YOU'RE ALREADY ON MAC.

I AM A LOW VISION SONAR USER. i HAVE MY MONITOR IN THE MINIMUM RESOLUTION REQUIRED FOR SONAR SO EVERYTHING IS AS BIG AS POSSIBLE ON THE SCREEN. i THINK THE MINIMUM RESOLUTION IS 1280 BY 800, THAT SEEMS TO WORK FOR ME ANYWAY. YOU CAN ALSO USE THE WINDOWS MAGNIFIER QUITE WELL WITH SONAR AND THEN YOU CAN MAKE THINGS AS BIG AS YOU WANT ON SCREEN. OF COURSE THEN THOUGH YOU CAN'T SEE ALL THE SCREEN AT ANY ONE TIME. 
 
THERE HAS BEEN ADDITIONAL SOFTWARE THAT YOU CAN USE WITH SONAR AND A SCREEN READER TO GIVE SPEECH OUTPUT. THE MOST WELL KNOWN ONE IS JSONAR THAT WORKS WITH JAWS. i HAVE TRIED TO ACCESS SONAR WITH A SCREEN READER CALLED NVDA AS CAKEWALK CLAIM TO HAVE BUILT IN ACCESSIBILITY FEATURES NOW. UNFORTUNATELY, THE ACCESS IN THIS REGARD IS NOT VERY GOOD. SO IF YOU HAVE SOME USEFUL VISION USE THE WINDOWS MAGNIFIER. 
 

Sonar 8.5 (which is an excellent DAW) has been adapted for low vision users by a company called Dancing Dots. I've never used it myself, but I imagine all the controls have been labeled with alt text so a screen reader can deal with it. My source for this is Sonar user jprykiel. He also told me there is another version, called jSonar. I don't know where to find either of these.
 
Best of luck.
