If a single USB port has failed but other USB ports are continuing to work on the Mac, even after an SMC reset, there may be an issue with that specific hardware USB port – you can either avoid using that USB port and instead use a USB hub for one of the other functioning ports, or you can have Apple run a hardware diagnostics test on the machine to determine if there is any hardware failure. The best mice you can buy in 2023 1. SteelSeries Prime Wireless: Best wireless mouse for any purpose

You can connect via Bluetooth or the included Logitech 2.4GHz USB receiver, and the Lift still works with Logitech’s Options software, with a flow feature that means you can work across multiple desktops or devices just by moving the pointer from one screen to the next. Plus, while it’s slightly disappointing that it’s powered by an AA battery rather than a built-in Lithium Ion cell, it’s concealed with the USB dongle behind a nifty magnetic plate. Well-designed, accurate, and available in three colours, this is the perfect ergonomic mouse for anyone with small to medium-sized hands. The other key issues are connectivity and sensitivity or resolution. Going for a wireless mouse means less cable clutter, which is useful if you’re using it with a laptop that you might be using at home, in the office and elsewhere. Some connect via Bluetooth while others connect via a plug-in USB dongle, which might be essential if you’re using a desktop PC, as many still ship without Bluetooth built-in.

If a device is not functioning on your Mac, the first thing you can do is reset the Mac SMC, a simple process which is slightly different depending on the Mac hardware. The ball moves with absolute fluidity in its housing and the buttons all have a satisfyingly positive action. The grippy feet on the bottom keep it firmly in place no matter what surface you use it on. The Ergo is not as versatile as some conventional mice – only the two secondary buttons and scroll wheel are programmable – but connectivity is not a problem with both Bluetooth and 2.4Ghz wireless on offer. It’s also good to see the Ergo M575 caters for Mac users as well as those who use Windows machines. Most people have the sensitivity dialled down – the high resolution just makes movement smoother and more accurate. Even professional gamers often won’t have the sensitivity maxed out; it’s just there if they need it for activities where pixel-perfect precision matters. Is there anything else worth looking out for? If, after an SMC reset, and after an NVRAM reset, none of the USB ports are working, and no USB device is working, something else is likely up with the Mac. With Bluetooth and 2.4GHz wireless connectivity, customisability via the Cherry app and 70 days of battery life (it recharges via USB-C), the MW9100 is a fantastic all-rounder. Cherry even supplies a little travel bag.

In all other respects, it’s a basic option – just the standard two buttons and scroll wheel, plus a button to step through the settings from 1,000dpi to the max, 1,800dpi. It connects via a 2.4GHz USB dongle – no Bluetooth support or switching – and is powered by two AAA batteries, which should last for around six months. It’s not what you’d call a luxury mouse, but at this price it doesn’t have to be. It feels good, it’s accurate, and it works without any fuss. If you’re looking for a step up from your bundled mouse, the MyDo is a tangible improvement.

In terms of features, it’s fairly basic by Microsoft standards – no fancy, customisable buttons, and just a simple up/down scroll wheel. It’s also Bluetooth only, with no facility to pair with multiple devices. Yet Microsoft’s optical technology ensures it works as well on a bare desk or kitchen table as it does on a mouse mat, and it’s accurate enough for everyday office and creative use. It’s a great mouse whether you’re at home or on the go.
