USB 3.0, released in November 2008, is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS) that can transfer data at up to 5 Gbit/s (500 MB/s after encoding overhead), which is about 10 times faster than Hi-Speed (maximum for USB 2.0 standard). It is recommended that manufacturers distinguish USB 3.0 connectors from their USB 2.0 counterparts by using blue color for the Standard-A receptacles and plugs,[2] and by the initials SS.[3]

USB 3.1, released in July 2013, is the successor standard that replaces the USB 3.0 standard. USB 3.1 preserves the existing SuperSpeed transfer rate, giving it the new label USB 3.1 Gen 1,[4][5] while defining a new SuperSpeed+ transfer mode, called USB 3.1 Gen 2[4] which can transfer data at up to 10 Gbit/s over the existing USB3-type-A and USB-C connectors (1200 MB/s after encoding overhead, more than twice the rate of USB 3.0).[6][7]

USB 3.2, released in September 2017, replaces the USB 3.1 standard. It preserves existing USB 3.1 SuperSpeed and SuperSpeed+ data modes and introduces two new SuperSpeed+ transfer modes over the USB-C connector using two-lane operation, with data rates of 10 and 20 Gbit/s (1200 and 2400 MB/s after encoding overhead). This specification has been renamed to reflect the evolution of "generations" of USB standards (i.e.: USB3.2Gen1 is "SuperSpeed", USB3.2Gen2 is also "SuperSpeed", but 2x faster, USB3.2Gen2x2 is also marketed as "SuperSpeed" but is 4x faster than 3.2Gen1). Nomenclature has been broadly criticized by both experts in the industry and the public at large for its confusing revisions not reasonably or appropriately reflecting the marketing messages that the guidelines prescribe in the standard specification, which is published at usb.org [8]

Apple Mac Support began in 2012?
USB 3.0 was introduced with the updated MacBook Air and MacBook Pro in mid-2012.
Support was first built into Mac OS X 10.7.3 "Lion" (Feb 2012) and later
so any osx version 10.7.3+ should support USB3.0 but this can get complicated on a hackintosh real quick

10.8 OSX Mountain Lion (Jul 2012 - Aug 2015)
10.7 OSX Lion (Jul 2011 - October 2012)

The first iOS device to support USB 3 through its Lightning port was the iPad Pro in 2015.

the sonnet allegro pci-e card states these requirements:
MAC: OS X┬« 10.8.5  or later; (released September 12, 2013)
PC: Windows® 8, 7, Windows Server 2012 or 2008

my pci-e usb3.0 adapter by ORICO states the following: Compatible with mac pro, 10.8.2+
