Hi - I have a late 2007 13 inch Macbook. It;s still a fantastic piece of kit.
I want to know if the new standard of USB 3.0 devices (like simple memory sticks) will work with my machine… are they compatible with USB 2.0 machines??
Partly I'm thinking of buying th newest standard now for the future
Phil
Yes, but it may interfere with WiFi. USB 2 won't do that.
Sorry… but how does it interfere with wifi??? I don't understand.

Thanks - would a USB memory stick also present a possible problem? Or just more complex devices?
OK - I tried some of the makers of USB memory sticks.
Kingston were hopeless and simply referred me to a huge document which talks about possible problems but does not mention USB memory sticks:

You may check the point number 9 " Electromagnetic Compatibility information to the user"
HOWEVER Corsair were much more straightforward about it . I asked:
"Hi - I have read lots about USB 3.0 "devices" potentially causing interference with wifi on some frequencies. I own a Macbook 2007. I am buying a new Corsaid USB memory stick... I know my Macbook wont get full use of the higher speeds. BUT it will help with moving data to other devices. BUT BUT is there a chnace the USB stick will interfere with my Macbook's wifi or bluetooth connections? thanks"
CORSAID SAID :
"Our USB drives do not emit any radio frequencies and therefore will not interfere with WiFi or bluetooth signals."
Phil
And just had live chat with Sandisk who say:
Cornilius L.: we have never heard of a USB memory stick causing radio interference
Based on this information, try Corsair, and if you see issues, inform them of your test results.
There are free WiFi signal test software out there for the Mac, which will tell you the strength of the frequency on a bar graph or chart. That could give you conclusive evidence one way or the other.
Note: some frequency interference could be due to damage of the USB port, cable, or housing and allowing leakage of the frequency. Now this would be more of a problem on a USB 3 compatible machine, but you could get a lemon Flash drive.
Will USB 3.0 work with 2007 Macbook
