Just a month into my Mac experience and so far have managed to solve most issues in transferring from Windows PC.

However, I need some help please with this issue, not sure if this is the right area to post in but here goes.

I use a third party provider to produce 360 degree virtual tours for me - I take the images and stitch them together, then upload the images to their website.

For some reason, I cannot complete the uploads if I use the iMac - my old windows machine still does the job OK which suggests it is not a problem with the website itself but a problem with the iMac or at least with OS X.

I have tried it using both Safari and Google Chrome - no joy with either.

Have called Apple support - this was my first experience of them and I have to say that sadly they were totally clueless!

Anyone out there who can help me please?
