One change that has found its way into MacOS Sierra that has been impacting a number of people is the removal of the user’s ability to easy exempt applications from Gatekeeper’s scrutiny. This is an issue when a user tries to open application is not signed by an “approved” developer. They will be prompted with a warning similar to this one:
After recently upgrading to OS X 10.12, I noticed some SMB file transfers were taking a lot longer than usual. Instead of the normal 100MB/sec transfer speeds I typically see between my Mac Mini and my Synology NAS on a gigabit (wired) network, I was seeing something closer to 30MB/sec.
Turns out I’m not the only one with this issue. Searching Google for “10.12 slow smb” returns pages full of results of people reporting the same issue. Most of them say “switch to AFP and the problem goes away.” That’s nice but I specifically use SMB because I have a share that’s accessed by Linux, Mac, and Windows – and so SMB is the right solution to keep file naming consistent.
The issue seems to come down to Apple’s SMB forcing default enabling of “client signing” which ruins performance. Continue reading
I recently made the decision to ditch my old Sonicwall TZ 205 in favor of the new Synology RT 1900ac. As a security guy, this seems like an odd decision, but since I was not paying for any of the advanced Sonicwall services, it really just came down to convenience and support. I run a Synology 1815+ at home and love everything about it, so I wanted to give their brand new router/firewall a shot. Unfortunately, I’ve run into some very strange firewall behavior that I’ve been trying to work through with their support team.
I guess I’ll start off with a little about what this blog is to me. Overall, this is just going to be a place where I can post helpful items for myself. Throughout my career in IT, I quickly came to the realization that no problem is so unique that someone else has not run into something like it before. There have been hundreds of blogs, forum posts, and listservs that have helped me over the years in the myriad of problems I have run in to. To give back to the community, I have decided to post my solutions to various problems I come across. I do this in the hopes that somewhere out there, another IT guy will be pulling his hair out, trying to solve some problem, and through the magic of the interwebs he will land on this site, which may provide him the hint he needs to solve whatever is vexing him, and make him seem a genius to his boss.
Please, feel free to use and distribute anything you find on this site for whatever your needs require. I wish you luck, fellow traveler, since I’m sure if you are on this site you are approaching desperation in your search for an answer to that problem someone on a forum somewhere experienced, solved, and then never bothered to share with the world what that solution was.
I leave you with one of my favorite comics from the geniuses at xkcd.com:
