Firstly, I have updated my Mid 2012 Macbook pro on High Sierra, since it was a free upgrade I downloaded and installed it thinking it would bring any good. But, I have started facing issues with it. My trackpad has gotten glitchy, at times it gets stuck and sometimes it starts moving on its own. I have no idea why is that happening. Secondly, I have been looking for a VPN service for mac, I have tried free VPNs but they don't work for me, the internet bandwidth cuts down to half and most of them also have limited bandwidth, so it has always been a struggle. I am willing to pay for the service but need recommendation which one will work the best, I usually stream and have concerns about my online privacy. There are so many out there so please give me a limited option. If it is affordable then it is a plus.
