When I open EOS Utility, an error pops up that says, "Cannot be used with this version of the operating system." Is there a work-around or a utility I can download so my camear &amp; Mac will work nicely together? (My Mac can no longer be upgraded, so I'm stuck with this operating system)</P> Wed, 14 Jan 2015 00:49:14 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/My-Macbook-Pro-system-10-9-5-doesn-t-support-my-new-Rebel-T3i/m-p/130846#M59879 mandystaver 2015-01-14T00:49:14Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/My-Macbook-Pro-system-10-9-5-doesn-t-support-my-new-Rebel-T3i/m-p/130849#M59880 Check here for software.<BR /><BR /><A target="_blank" href="http://www.usa.canon.com/cusa/support/consumer/eos_slr_camera_systems/eos_digital_slr_cameras/eos_rebel_t5i_18_55mm_is_stm_lens_kit#DriversAndSoftware">http://www.usa.canon.com/cusa/support/consumer/eos_slr_camera_systems/eos_digital_slr_cameras/eos_rebel_t5i_18_55mm_is_stm_lens_kit#DriversAndSoftware</A> Wed, 14 Jan 2015 02:08:42 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/My-Macbook-Pro-system-10-9-5-doesn-t-support-my-new-Rebel-T3i/m-p/130849#M59880 jrhoffman75 2015-01-14T02:08:42Z
