Broadband users should take no chances when it comes to selecting a dongle for use with their computer, it has been claimed.
According to Electricpig.co.uk, many of the devices are not compatible with the Apple operating system Snow Leopard, meaning it is necessary for buyers to be extremely thorough in their approach.
The website urges consumers to always check the small print thoroughly on dongle deals.
"If it says it works with a Mac, check which version. OS X Snow Leopard is 10.6. If you're unsure, ask before laying down your cash," it added.
Valuable advice may be available on internet support pages, the site said, while local broadband vendors may be able to offer further guidance.
Earlier this week, Electricpig.co.uk reported that dongles offered by several providers including 3, T-Mobile and O2 all fail to work with Snow Leopard at present.
