This is a bootable installer drive for Mac OS 10.7, 10.8, 10.10, 10.11, 10.12, 10.13, 10.14, 10.15, 11, 12, 13, and 14 (Lion all the way through to Sonoma) The size of the USB drive is 256gb Can be used to upgrade older system to any OS from Lion up to Sonoma (as long as it is officially supported by Apple) I do offer faster shipping options than USPS Ground Advantage, but they do require you to pay a shipping fee. If you purchase one of these options, my handling time will be either same-day as the order, or next day, just depends on when the order is placed. Please reach out to me if you have any further questions regarding this listing. I want you to walk away from this transaction happy and with your equipment in good, working condition.
