Guys, The Kernsafe iSCSI initiator can be taken off this list in my opinion. The product is a proprietary solution, and only works with their San (Target) software. Css rcon hack.

I'm looking for a good iSCSI initiator to connect some Macs (currently running 10.12.5) to iSCSI targets hosted on a Synology NAS (latest DSm version). I have found the products from globalSAN and ATTO.

You cannot use this product for connecting to any other vendors iSCSI targets such as a NAS from Synology, or Netgear, etc. I see a lot of people talking about it, but I'd say that not a lot of people have used it. If one did, they would very quickly realise that it won't work.

It does not discover any other vendors iSCSI targets at all. Looking at the forums on their website, a number of people have asked for support, but Kernsafe have finally responded with a strange message suggesting Apple are no longer providing Certificates to 3rd parties.??

I have posted a question that has not been approved by the moderator yet, asking to clarify the situation, but I suspect we'll be waiting a while to see that post. Regards BL . From the site's page: ' Disable kext signing before attempting to install the initiator. Prior to El Capitan (that is, OS X versions 10.10 and below), this is achieved by running sudo nvram boot-args=kext-dev-mode=1 In El Capitan, this is achieved by running csrutil disable at the Recover OS terminal window (see the System Integrity Protection Guide for more details). In both cases, a reboot is required.'

That should make it a non-starter (certainly so for any of my clients) as far as I'm concerned. Atto's software (although $195.00) has always been well-regarded and recommended. I don't think singing it yourself would satisfy SIP, I think it has to be signed by Apple to get past it but I could be wrong. Disabling SIP isn't really that big of an issue for me but YMMV.

I'd like to try iSCSI Initiator 1.0.0-beta2 out myself but I haven't had any luck getting the the installer to build, a couple of the modules fail to build and thus the.pkg isn't complete and fails it's post install script. I'm building on 10.11.5 with Xcode 7.3.1. I'll file a bug on the github and see if I can get it sorted, I'd really like to try this out.. The current version of KernSafe does claim to work with Yosemite. I downloaded it and I can discover my target. (At least if I tell it to be visible without CHAP -- while CHAP is offered for the data session, they don't seem to support it for the discovery session.) Unfortunately, I can't log in because the initiator appears to treat an iSCSI Redirect message as an error. That's a violation of the spec: the RFC is very clear that redirect is not an error.

And since my target always uses redirect, it seems I'm stuck.
